|Abstract:||,akhni,wali .. Peeliwaii hill of Madan Kudhan section of thetr5. Upper. Felt of Rajasthan have been studied w .th especial emphasis on structures and miners. lisati.on,, The ridge comprises of the rock formations belonging to .. ahgarh series of Delhi system, These rocks ha,ve been intruded by magnetite .S amphibolites and per meated by mines ali.zing solutions. The recent unit comprise of Gosssan bard, occurring in enechelon pattern, alluvium and wind blown sands. Various rock types show the effect of regional metamorphism hav .ng typical mineral assemblages of amphibollte facies'. The xetrogre live metamorphism is indicated by seri.citization and c' lorit . nation. Fe-Mg me banomati sm has c1 i volop ed typical anthophyllite -curving_ tonite assemb .ac o, Based up ,n the study of the regional structures and structural analysis of the area, It has been concluded that the rocks have been deformed by the stresses acting from about N 130 and N 310 directions, producing anticline with regional axis trending N 400 and plunging towards north. These stresses have produced various sets of tension and shear joints, faults and smaller folds during differgr^'= stages of defornation. The presence of only few metal Cons like Fe, cu, Wo, Ti In thispart, as compared to many metallic ions present in the southern port of the belt, have Indicated that the minerslisatton took place probably at an early stage of suiphids activity in this part at about 4 A. The granite present all slona the belt might have acted as the source to give rise the hydrothermal, solutions. Various structural features have predominated over the lit alogicel features In the ore localization. The faults have served as Important channolwa js for t t.e vement of minereli s .ng solutions, and at places have been mineralised. Bedding joints have been most Important loch i for mtneral.tzetion, *port from the schistos ty, giving various vein patterrte. The Ore reserve calculations of this belt have indicatedhuge reserves, &mounting to about 60 million tons for this section. So for no attempt has been made to estimate the ore reserves at Lakhntwsli - Peeliwalt hill due to lack of presence of sufficient data.|
