| DOWSING We try to separate this method by its paranormal connotation and to underline its advantages in the geological practice using an approach, in our opinion, scientific and realist. We support this matter, extremely sensitive and disputed, pleading for an ignored and disregarded geological method, whose results can be exceptionally sometimes. Many peoples reject this method mainly because of its, sometimes, irreproducible character, as well as the differences that occur between operators.
| |||||||||||
Every bio-perturbing geological body generates different dowsing signals. Generally, the signals overlap, their separation being done according to the specificity and the experience of the operator. The mineralized veins or dykes (for example lamprophyres) show a short maxim (a raise of the rod) when an operator crosses them. The faults produce a complex signal. Vertical faults show a symmetrical signal. The inclined faults show an asymmetrical signal, consistent with the inclination of the faults, so we can determine the direction of the fault's inclination. The underground water flows generate a maxim during the crossing point; the rod drops when we go downstream and raises when we go upstream. The drifts and other underground holes can be detected by the sudden descent of the rod. For each petrography type correspond one position of the rod (Zolya Laszlo). The veins, faults, underground water flows, drifts and the petrography contacts direction can be measured either by following them, step by step, or crossing them in many points.

1. DOWSING RESEARCH IN THE ZEBRAC - MERMEZEU ZONE
The indicator dowsing signal for mineralized zones (and/or hydrothermal transformed) was discovered (developed) by Lucian Ionescu. The signal has a sinusoidal character, with alternative tendencies of turning one way or the other (up or down) of the rod. The turning period grows proportionally to mineralization intensity and/or hydrothermal transformations. The dowsing anomalies map is drawn by interpolating all zones with the same value (length) of the signals (up or down). In this example, the maximum dowsing anomalies cover the zones having the signal lenght of 100 - 150 double step. The signal length in the poorly mineralized zones is 1 / 50 double step. ("Double step" is a measurement method in the field, determining the distance by counting only the steps taken with the same foot.)
The eruptive andesitic structure Zebrac - Mermezeu (South of Calimani Mountains, East Carpathians) containing poorly auriferous vein mineralization and disseminated lead - zinc, were intensely investigated by geological, geochemical and geophysical (gravimetric, magnetometric, electrometric and radiometric) prospecting, with drillings and with underground works.

Vârful Ursului (Bear's Peak) is marked by a moderated dowsing anomaly, surrounded by a maximum belt. The explication is that Bear's Peak is a newer and fresh intrusion surrounded by an older hydrothermal transformed zone. In the Zebrac Valley, upstream from Ursu Creek, one vein was identified, explored using underground works as well. This vein generates the north-south maximum dowsing anomaly and represents a segment of the maximum anomaly described above. The mineralized veins from Ursului Peak and from other zones are located on faults. The hydrothermal transformations and mineralization from Mermezeu, Paltinis and Popii creeks, accompanied by dowsing anomalies, are the result of hydrothermal circulations on faults. The maximum dowsing anomalies are greatly correlated with geophysical (geoelectrical and magnetometerical), and also with geochemical ones. In general, the weak dowsing anomalies correspond to the non-mineralized pre-volcanic fundament, or a minimum geoelectrical corridor (as in the Popii Creek - Paltinis Creek and North Paltinis Peak zone).
Conclusions: In this moment the method is not rigorously adjusted for placing underground works based on dowsing information only, but it has good results in preventing the wrong placement of theses. We don't know all causes that can generate dowsing anomalies, but we claim that a metallic mineralization, accompanied or not by hydrothermal zones, cannot exist without dowsing anomalies. This research method requires modest technical equipment, it is low cost and fast, and produces complex results.
2. DOWSING RESEARCH IN THE OBCINA PEAK - CIBENI BROOK ZONE
The perimeter is situated south-west of Tulghes, Harghita county, on the left slope of Putna Valley. It outcrops metamorphic rocks belonging to Tulghes Group, Balaj tectonic zone and Bretila Group. Lamprophyres dykes sporadically occurs.

Additional information obtained by using dowsing method:
1. More faults identification (the map shows the more important ones); the east - west faults have great implications for relief mould; every torrent or brook is installed on top of a fault; faults, and especially their intersections favor the underground water ascension (springs, marsh); sometimes, upstream, the dowsing signal is for underground water flood and downstream the signal is for fault.
2. The majority of petrologic types can be differentiated by dowsing method
3. In the Obcina Crest zone, there are known two short gallery marks, dug by former Rare Metals Company in order to investigate two veins weakly mineralized with REE and common sulfurs (mineralization I); a maximum dowsing anomaly develops in their zone that extends toward south-east; new mineralization were identified due to the investigations intensified in the maximum dowsing zone.
As a rarity, we mention the witness dowsing method. In practice, we held in our hand a small piece of mineralization, and we noticed that all other dowsing signals, formerly identified, disappeared, except one, a vein type signal (replacing an old fault signal).
In the Obcina Crest zone, the former Rare Metal Company investigated two veins weakly mineralized with common sulfurs and REE (mineralization III on map) using two galleries. The veins are quasiconcordant with quartz-sericite schist, and have opposite inclination (toward west). The vein investigated using Gallery 1 is accompanied by a lamprophyre dyke (both with the same position: 260°/50°) and dowsing signal was pursued 400 m toward south-east. The mineralization investigated using Gallery 2 is weaker, representing the discontinuous filling of a fault. North of the Obcina Crest, the dowsing signal is fault type, and vein type to south.
In the field, we marked the Gallery no. 1 zone with a topographical network survey having 25 m gauge. Using dowsing method, we covered this network and identified faults, veins and the gallery. For each fault we measured its direction and we determined its inclination. The following pictures show the raw data of the dowsing measurements and their interpretation. Notice the pronounced tectonically fragmentation, and the predominance of faults orientated WNW - ESE. Also notice a gradually growing distance between the vein signals (that incline toward west) and gallery signals, proportionally with the distance increase between gallery and the surface elevation.

Legend: dowsing signals for: 1. Fault, 2. Vein, 3. Cavity (gallery)
The research done with László Zólya during the summer of 1998, was about the dowsing investigation of mining field Jolotca (molybdenum, REE, common sulfides etc.). Banya zone is situated north of Jolotca, NW of Ditrau alkaline Massif. In order to clarify, using dowsing method, the geological context where a mineralized vein occurs, we marked a topographical network survey. An old sided-gallery, had unconvincing results.
Banya zone is situated in the proximity of Ditrau alkaline Massif, mineralized veins being found in the cornificated crystalline schist. Using dowsing method, we tried to find out the zone tectonics and to verify the extension of mineralized vein identified in surface prospecting shafts. We marked a zone of about 0,5 Km2 with a topographical survey network of 100m gauge. We covered all alignments, localizing and measuring all dowsing signals.
In the beginning, dowsing signals seemed to have a chaotically distribution, but, in the end, dowsing signals correlated well. In the middle, in the prospecting shafts zone which intercepted one mineralized vein, we identified a vein type dowsing signal, expanding towards SW and NE. We found other two vein type signal, suggesting the presence of joints veins, similar to the Jolotca underground works. We assume that the vein type signal from "J" meridian, between "4" and "5" parallels, represents the continuation of the main mineralized vein (red on the map), which was fall out 130m toward south. This tectonic accident, orientated north - south, might be the Teasc fault identified and measured (having same value) in the underground work at Jolotca (Teasc zone).
 | Dowsing sketch of Banya zone Legend: 1. temporary torrents, 2. spring; Dowsing signal types: 3. vein, 4. vein (mineralized, intercepted by the surface prospecting shafts), 5. fault, 6. underground water flows, 7. cavity (gallery); Dowsing anomalies: 8. maximum, 9. medium, 10. weak |
We identified and localized two cavity type dowsing signals; the first one for gallery no. 22, and the second, probably, the end of gallery no. 20 which came from south. In the central-south part of the zone, we intercepted a signal similar to the underground water flows, and few meters underneath, a spring occurs at faults crossing.
The maximum dowsing anomalies have a great increase in the mineralized vein of Jolotca zone, and strong decrease at the periphery of the massif and in the neighboring metamorphosed formations. In the Banya zone, the maximum dowsing anomalies follow the mineralized veins, and the diminution of anomaly toward NE, suggest the end of mineralization.
