... sample CCI-L03 generally has different texture, where it mainly composed by intergrowth of equigranular crystal (Fig. 5). It has similar texture with diabasic rock that is sub ophitic texture where the pseudomorph crystal grow in the interstitial space of plagioclase laths. This sample has the different composition with those sample above. It mainly composed by plagioclase, labradorite in detail and olivine which has pseudomorphed by iddingsite which ...
