In this researcH, the trace-element geocHemistry of native and common plant species in Ireland sucH as ash, beecH, blackberry, Hawthorn, oak, poplar and sycamore was systematically determined above the Navan Zn-Pb deposit (Ireland), cUrrently mined by Boliden Tara Mines Limited. THe study area represents a sub-oUtcropping carbonate-Hosted base˗metal ore body characterised by a large shallow soil Zn- Pb anomaly. The new results show that Zn contents in leaf materials across all species vary from 18 ppm to 700 ppm (dry weigHt). THe HigHest concentrations of Zn are observed in poplar trees growing above subcropping mineralization. Levels of Pb and Cd are anomaloUsly HigH in all investigated tree species grown in soil witH metal anomalies, compared to the backgroUnd values from control sites. In this study, focUs was also placed on Hawthorn and oak as a representative plant species Used for spatial and temporal vectoring. Using trace- element analysis, anomalies can be detected, bUt Uncertainties remain concerning their soUrces. In order to better Understand anomaly soUrce several models of Cu and Zn isotope data will illustrate the typical ranges of metal stable isotopes one migHt expect in diverse geological, and botanical setting. -

In this study Vegetation of Iron mine showed very sparce and comprises theory scrubs and very few tree species, with Semi-evergreen nature. Ninty four species belonging to 80 genera of 30 angiosperm families were recorded on Iron mine. Eight species showed the highest percentage of presence values on Iron mine Schouwia purpurea possessed the highest percentage of presence, density and higher abundance and higher levels on iron accumulation. As Schouja purpurea is the costant species, it may be considered as a local indicator plant for Iron. Key words : Iron mine, constant species, local indicator plant. INTRODUCTION Plants growing on mines and mine relics have been found to accumulate and tolerate unusual concentration on metals. These metal to learnt species as indicator plants have attracted the attention for prospecting the mineral deposits. Individual species or vegetation types are known to act as indicators of are deposits in geobotanical prospecting. Several investigators have recognized different plant associations on varying geologic substrates. Koch(1932) studied in detail the communities growing on zinc and copper contaminated soils. Similarly many geobotanists have reported on the exclusive occurrence of certain plant species and their associations on metal rich soils ( Aery 1977; cole 1965; Nesvetayalova 1961; Tiagi & Singh 1973; Venkatesh 1964: Veeranjaneyulu & Dhanaraju GEO BOTANICAL STUDIES ON OBULAPURAM IRON MINE 1P a g e 1990) Ernst (1966) has successfully classified plant communities on soils containing heavy metals according to Braun – Blanquet (1932) approach. -

Silver Enrichment in the San Juan Mountains, Colorado
SILVER ENRICHMENT IN THE SAN JUAN MOUNTAINS, COLORADO. By EDSON S. BASTIN. INTRODUCTION. The following report forms part of a topical study of the enrich ment of silver ores begun by the writer under the auspices of the United States Geological Survey in 1913. Two reports embodying the results obtained at Tonopah, Nev.,1 and at the Comstock lode, Virginia City, Nev.,2 have previously been published. It was recognized in advance that a topical study carried on by a single investigator in many districts must of necessity be less com prehensive than the results gleaned more slowly by many investi gators in the course of regional surveys of the usual types; on the other hand the advances made in the study of a particular topic in one district would aid in the study of the same topic in the next. In particular it was desired to apply methods of microscopic study of polished specimens to the ores of many camps that had been rich silver producers but had not been studied geologically since such methods of study were perfected. If the results here reported appear to be fragmentary and to lack completeness according to the standards of a regional report, it must be remembered that for each district only such information could be used as was readily obtainable in the course of a very brief field visit. The results in so far as they show a primary origin for the silver minerals in many ores appear amply to justify the work in the encouragement which they offer to deep mining, irrespective of more purely scientific results. -
Principles of Geochemical Prospecting
Principles of Geochemical Prospecting GEOLOGICAL SURVEY BULLETIN 1000-F CONTRIBUTIONS TO GEOCHEMICAL PROSPECTING FOR MINERALS PRINCIPLES OF GEOCHEMICAL PROSPECTING By H. E. HAWKES ABSTRACT Geochemical prospecting for minerals includes any method of mineral exploration based on systematic measurement of the chemical properties of a naturally occurring material. The purpose of the measurements is the location of geochemical anomalies or of areas where the chemical pattern indicates the presence of ore in the vicinity. Anomalies may be formed either at depth by igneous and metamorphic processes or at the earth's surface by agents of weathering, erosion, and surficial transportation. Geochemical anomalies of deep-seated origin primary anomalies may result from (1) apparent local variation in the original composition of the earth's crust, defining a distinctive "geochemical province" especially favor able for the occurrence of ore, (2) impregnation of rocks by mineralizing fluids related to ore formation, and (3) dispersion of volatile elements transported in gaseous form. Anomalies of surficial origin-^secondary anomalies take the form either of residual materials from weathering of rocks and ores in place or of material dispersed from the ore deposit by gravity, moving water, or glacial ice. The mobility of an element, or tendency for it to migrate in the.surficial environment, determines the characteristics of the geochemical anomalies it can form. Water is the principal transporting agency for the products of weathering. Mobility is, therefore, closely related to the tendency of an element to be stable in water-soluble form. The chemical factors affecting the mobility of elements include hydrogen-ion concentration, solubility of salts, coprecipitation, sorption, oxidation potential, and the formation of complexes and colloidal solutions. -

It is intended to serve as a basis for evaluating the current state of the art and research priorities with respect to prospec~ ing for mineral deposits in tropical regions. This activity area was selected for analysis due to (1) its importance in the development context; (2) the relative neglect of research in the area by donor countries and international agencies; and (3) the likelihood that additional research will make major contributions to the solution of critical problems. This Report is based largely on a preliminary analy sis prepared by the U.S. Geological Survey for the Agency for International Development!! and comments subsequently received from numerous reviewers in U.S. Government agencies and universities, other donor countries, and international development institutions.
