    • Abstract:
      The type of gold deposit in the research area in Brambang Village, Lombok Island, West Nusa Tenggara can be interpreted from several things, including fluid inclusions.This type of gold deposit is very important to know related to the potential gold deposits in this area. The lithology unit in the Brambang area can be divided into several lithological units considering their lithological dominance: lapilli tuff, diorite, tonalite and diatreme breccia. There are three types of veins observed where there are the fluid inclusions samples are taken, namely vein types A, B and C from the vein zone in tonalite rocks. The results of salinity measurements show two temperature groups that can be adjusted with vein type A-B for a temperature of ~550 oC and vein type C for a temperature of ~250 oC, these temperature magnitudes indicate the type of porphyry mineralization associated with base metals. ; Dari inklusi fluida daerah penelitian di Desa Brambang Pulau Lombok Nusa Tenggara Barat ditafsirkan tipe endapan emas di Daerah tersebut. Tipe endapan emas ini sangat penting untuk diketahui karena sangat berkaitan dengan potensi endapan emas di Daerah ini. Satuan litologi daerah Brambang dapat dibagi menjadi beberapa satuan batuan dengan mempertimbangkan dominasi litologinya yaitu: satuan tuf lapilli, satuan diorite, satuan tonalit dan satuan breksi diatreme. Ada tiga tipe urat yang diamati dimana terdapat inklusi fluida yaitu tipe urat A, B dan C yang diambil dari zona urat pada batuan tonalit. Hasil pengukuran salinity menunjukan dua grup temperatur yang dapat disesuaikan dengan tipe urat A-B untuk temperatur ~550 oC dan tipe urat C untuk temperatur ~250 oC, besaran temperature tersebut mengindikasikan tipe mineralisasi porfiri yang berasosiasi dengan logam dasar.
