Abstract
ABSTRAK
Daerah penelitian terletak di Kecamatan Kuala Behe, Kabupaten Landak,
Provinsi Kaliamantan Barat. Daerah ini diketahui terdapat aktivitas penambangan
emas yang dilakukan oleh masyarakat lokal, sehingga lokasi ini memiliki indikasi
adanya mineral logam yang berkaitan dengan sistem hidrotermal, namun
karakteristik geologinya belum diteliti secara detail. Penelitian ini bertujuan untuk
mengkaji kondisi geologi, tipe alterasi, dan sebaran mineralisasi logam di daerah
tersebut. Metode penelitian yang digunakan adalah pemetaan geologi, alterasi, dan
mineralisasi, serta pengambilan sampel batuan untuk analisis laboratorium meliputi
analisis petrografi, mineragrafi, dan x-ray diffraction. Stratigrafi daerah penelitian
dari tua ke muda tersusun atas satuan serpih Pedawan, satuan konglomerat Kayan,
Andesit Sintang dan Diorit Sintang. Zona alterasi yang hidrotermal yang berkembang
terdiri atas potasik, propilitik, filik, argilik, dan silisik. Mineralisasi utama yang
ditemukan berupa pirit, kalkopirit, magnetit, dan hematit yang ditemukan secara
diseminasi dan pengisian rekahan. Berdasarkan kondisi lapangan dan pengolahan
data serta diperkuat dengan analisis laboratorium, hasil penelitian mengindikasikan
bahwa daerah penelitian memilki potensi endapan porfiri. Oleh karena itu, daerah
penelitian memiliki potensi positif terkait keberadaan mineral logam yang harus
dikelola dengan regulasi yang baik.

ABSTRACT
The research area is located in Kuala Behe District, Landak Regency, West
Kalimantan Province. This area is known to have gold mining activities carried out
by the local community, so this location has indications of metal minerals related to
the hydrothermal system, but its geological characteristics have not been studied in
detail. This study aims to examine the geological conditions, alteration types, and
distribution of metal mineralization in the area. The research methods used are
geological mapping, alteration, and mineralization, as well as rock sampling for
laboratory analysis including petrography, mineragraphy, and x-ray diffraction
analysis. The stratigraphy of the research area from old to young is composed of
Pedawan shale units, Kayan conglomerate units, Sintang Andesite and Sintang
Diorite. The hydrothermal alteration zone that developed consists of potassic,
propylitic, phyllic, argillic, and silicic. The main mineralization found is pyrite,
chalcopyrite, magnetite, and hematite which are found by dissemination and fracture
filling. Based on field conditions and data processing and reinforced by laboratory
analysis, the results of the study indicate that the research area has the potential for
porphyry deposits. Therefore, the research area has positive potential related to the
existence of metal minerals that must be managed with good regulations.
