Abstract

Age old gold panning along the streams, ancient workings for gold mineralization in the quartz veins emplaced in Malanjkhand granitic pluton (MG) along the peripheral contacts of older rocks of Amgaon Gneiss (AG) and Nandgaon Volcanics (NV) besides shear controlled zones drew the attention of present authors to take up detailed survey. These quartz veins are the locales for future exploration of copper-gold mineralization. Garhi Dongri (Gd) and Khandapar (Kdp), occuring at the peripheral contacts, may be gold rich and copper poor in mineralization and are very significant Gidori (Gd) and Pipardhar (Pd) areas, falling within sheared zones, may be considered as prospective sites for Malanjkhand-type rich copper and poor gold mineralization. Shitalpani(Stp) and Kundikasa(Kd) may fall under poor copper and/Or poor gold categories. GD prospect is found to be a promising for gold mineralization. Stp is under investigation and preliminary results suggest that it may be a poor-copper(?) prospect. Mineralogical association and alterations in GD and Stp are very similar to mineralogical alterations at Malanjkhand porphyry copper deposit. Gold rich and gold poor deposits are known in the northern chilean belt of porphyries and many other porphyry deposits.

Abstract

The use of indicator plants and plant organs have been considered as a tool for mineral exploration as early as in eighth century. In the present paper, the data on the biogeochemical studies of the plants growing in three copper prospecting areas of Madhya Pradesh are presented. The areas are near Gidori, Pipardhar and Garhi Dongri villages within Malanjkhand granitoid, situated to the south of Malanjkhand porphyry copper deposit. Nineteen plant species abundant in these areas were chosen for chemical analysis of their organs for copper. Analyses indicated that Jangli Tulsi (Hyptis suaveolens, (L.) Poit) plant, with their stunted growth, act as an indicator plant for copper rich soil. High copper concentration in some of their organs are observed. Kurlu tree (Sterculia urens, Roxb ) is found to be a good metal accumulator plant among others for base metal exploration. These observations can help as a supplementary guide for exploration of copper and other metals in this vast soil covered area.
