Abstract
Daerah penelitian terletak di daerah Mamput dan sekitarnya, Kecamatan Kapuas Tengah, Kabupaten Kapuas, Provinsi Kalimantan Tengah. Secara geografis terletak pada 1130 18’ 33” - 1150 43’ 38” bujur timur dan 00 41’ 23” lintang utara – 234’ 08” lintang selatan. Daerah telitian memiliki luasan 5 x 3 km2 dengan skala peta
1:12.500 yang berlokasi pada daerah konsesi tambang PT. Pama Persada Nusantara.
Satuan geomorfologi daerah penelitian antara lain satuan geomorfik bukit
intrusi (V1), satuan perbukitan karst (K1), satuan geomorfik perbukitan struktural
(S1), satuan geomorfik perbukitan curam (S2), satuan geomorfik lereng
homoklin(S3) dan satuan geomorfik tubuh sungai. Pola pengaliran berupa pola sub
dendritik. Daerah penelitian dibagi menjadi 5 (lima) satuan batuan. Urutan dari tua
ke muda sebagai berikut: satuan sekis Busang (Kapur Akhir), satuan sekis Tanjung
(Eosen Awal), satuan batupasir Tanjung (Eosen), Litodem Andesit (Eosen Akhir).
satuan batugamping Berai (Oligosen Awal – Oligosen Akhir), Struktur geologi yang
ditemukan pada daerah penelitian berupa lipatan Antiklin dan Sinklin, serta didapati
berupa kekar-kekar dengan arah umum tegasan relatif timur laut - barat daya.
Berdasarkan analisis aspek fisika, kimia, dan biologi yang telah
dilakukan,satuan batupasir Tanjung diendapkan pada lingkungan Lower Delta Plain
sampai Transitional Lower Delta Plain dengan fasies pengendapan crevasse splay.
Analisis lingkugan pengendapan melalui analisis polen dan maseral memiliki
keterkaitan, dimana dapat di tarik kesimpulan bahwa lingkungan pengendapan
batubara pada daerah telitian adalah Marsh sampai Backmangrove.
The study area is located in Mamput and the surrounding area, CentralKapuas District, Kapuas Regency, Province of Central Borneo. Geographicallylocated at 1130
18 '33 "- 1150 43' 38" east longitude and 00 41 '23 "north latitude -20 34' 08" south latitude.
Unit geomorphology research areas include intrusion hill geomorphic unit (V1), karst hills geomorphic unit (K1), structural hills geomorphic unit (S1), steep
hills geomorphic unit (S2), the slope of homoklin geomorphic unit (S3) and stream body geomorphic unit, Drainage pattern in the form of sub dendritic patterns. The
study area was divided into five (5) lithologies. Sequence from young to old as follows: Busang schist unit (Late Kapur), Tanjung shale unit (Early Eocene),
Tanjung sandstone unit (Eocene), Litodem Andesite (Late Eocene), Berai limestone
unit (Early Oligocene - Late Oligocene), geological structure found in research
areas such as folds anticline and syncline, and found to be a folds with the general
direction of the shear relative northeast - southwest.
Based on the analysis of aspects of physics, chemistry, and biology that has
been done, Tanjung sandstones unit deposited on the environment Lower Delta Plain
until Transitional Lower Delta Plain with crevasse splay facies sedimentation.
Precipitation of environmental analysis through the analysis of pollen and maceral
have relevance, which can be deduced that the depositional environment of coal in
the region are carefully situations Marsh until Backmangrove.
