The calculations of ore reserves in the Borov Dol deposit were mainly carried out with support AutoCAD software package, and those results received official confirmation Republic North Macedonia. latest calculation using MICROMINE provides a wider range use source data from detailed geological surveys rapid correlation between metals associated elements deposit. procedure for consists several s...

The Sungun porphyry copper deposit that intruded Eocene volcano sedimentary and Cretaceous carbonate rocks hosted by a diorite/granodioritic to quartzmonzonitic stock. Copper mineralization is essentially associated more with potassic and less phyllic alteration. Therefore separating these two kinds of alteration is so important. In this paper, by applying the discriminant, it was attempt to se...

In this presentation questions are raised about a melt-restite unmixing model proposed by Barton and Sidle (1994) for the myrmekite-bearing Waldoboro granite complex along the southeastern coast of Maine (USA). This complex consists mostly of granite/granodiorite gneiss and granite, but smaller masses of quartz diorite, aplite, pegmatite, leucogranite, tourmaline granite, and granite porphyry o...

Porphyry deposits are the dominant sources of copper and major several base precious metals. They commonly formed via repeated emplacement hydrous magmas associated fluid exsolution. As a result, mineralized hydrothermal veins may undergo multiple deposition reopening processes that not fully accounted for by existing models. The Tongchang porphyry Cu deposit is rare example being related to si...

Hyperspectral remote sensing records reflectance or emittance data in a large sum of contiguous and narrow spectral bands, and thus has many information in detecting and mapping the mineral zones. On the other hand, the geological and geophysical data gives us some other fruitful information about the physical characteristics of soil and minerals that have been recorded from the surface. ...

Abstract A current mineral exploration focus is the development of tools to identify magmatic districts predisposed host porphyry copper deposits. In this paper, we train and test four, common, supervised machine learning algorithms: logistic regression, support vector machines, artificial neural networks (ANN) Random Forest classify metallogenic ‘fertility’ in arc magmas based on whole-rock ge...

A sixty-three day study was conducted with young men confined to a metabolic unit to study the effects of a-cellulose and phytate on copper absorption. Copper absorption was determined with 6tCu, a stable isotope of copper, during each of 3 dietary treatments (basal diet, basal diet + a-cellulose, or basal diet + phytate). The addition of a-cellulose or phytate to the basal diet did not affect ...
