Struktur Geologi dan Sebaran Batubara daerah Bentian Besar, Kabupaten Kutai Barat, Propinsi Kalimantan Timur
Abstract: This study is a
surface geological mapping work to determine the geological conditions in the
study area and in particular the presence of coal of Bentian Besar District,
West Kutai Regency, East Kalimantan Province. The goal is to determine the
position and spread of coal layer, coal quality and quantity of coal resources
in the study area. Research on the existence of coal deposits is done through
field survey methods, by observing, define and measure elements of geological
structures encountered. At this stage of field work carried identification,
observation, measurement of the coal position and takes it sample. In the study
area encountered 2 (two) rock formations, Pamaluan, and Pulubalang Formation.
Coal deposits found in rock unit known as Pulubalang Formation. Direction of
the dip of the rock layers in the study area form a syncline structure. At this
structure of the coal seam, there are three dip directions, namely: rocks on
the southeast side of syncline axis tilted toward the northwest, rocks on the
northwest side of the syncline axis tilted to the southeast, while the dip of
the rocks on the southwest side Syncline tilted toward the northeast.
