There are 3 Steps involved in it
Step: 1
A Sample no1 The given sample is a white coloured massive rock composed of carbonate minerals calcite andor dolomite The rock shows sugary appearance and as it is quite fine grained individual crystals cannot be identified and hence the number of crystals cannot be specified The different kinds of minerals present in order of decreasing abundance are as follows The white carbonate part can be calcite or dolomiteowing to its white colour The lustre cannot be prominently determined from the image It appears vitreousin which case it is dolomite hardness is 35 to 55 otherwise calcite where it shows pearly lustre and hardness 25 to 35 The golden part this part seems to be chalcopyrite owing to its brass to golden yellow colour resembling gold and metallic lustre is mainly occurring as distorted crystals here It is a copper iron sulphide mineral crystallizing in tetragonal crystal ...
