Petrography and XRD mineral dolomites, paciran formation, district of Lamongan, East Java
Abstract
Limestone area research in Paciran area has attracted many geologists. Limestone Paciran is known to have more dolomite composition than limestone located in Tasikmalaya or other areas. The limestone facies in the area consisting of Grainstone, Packstone, and wackestone. These research methods are petrography, micropaleontology and XRD. Petrographic analysis shows that the diagenetic process has occurred, dissolution, dolomitization, and cementation. XRD analysis on the dolomite limestone are almost 31.02%, Micropaleontological analysis shows the fossils of large fores of the type of lepidocyclina which have been filled with cement and pieces of algae. The purpose of this research is to determine the composition of the dolomite minerals contained in the Paciran formation. At this time the limestones Paciran continues to be explored by miners for mining needs, dolomite as building construction, cement making, neutralizing acid in the chemical industry, magnesium and calcium sources in animal feed, flux in metal processing industry, glass making base material, ceramic, as fertilizer in the paper industry.
