Abstract
This study focuses on a host rock of the Suwan Prospect located about 6 km northwest of the Chatree gold mine in Phitsanulok-Phichit Provinces, Central Thailand. Gold-silver mineralization occurs as veins and stockworks hosted in volcaniclastic and volcanogenic-sedimentary rocks of Late Permian-Early Triassic age which is classified as a low sulfidation epithermal deposit base on mineralization texture, alteration pattern and sulfide mineral assemblages. Detailed field and petrographic observations of the main volcanic lithofacies of its hosted stratigraphic succession were carried out. From top to bottom, the hosted volcanic succession can be divided into 3 units, namely 1) Felsic volcanic unit (Unit 1), 2) Volcanogenic-sedimentary unit (Unit 2), and 3) Porphyritic andesite unit (Unit 3). Unit 1 consists predominantly of quartz-rich fiamme breccia, lithic-rich fiamme breccia and feldspar-phyric rhyolite breccia. The volcanogenic-sedimentary unit (Unit 2) consists of fine to coarse-grained sandstone, sandy-matrix polymictic breccia, polymictic intermediate-felsic breccia, mudstone and limestone lenses. Unit 3 comprises plagioclase-phyric andesite, plagioclase-hornblende-phyric andesite and monomictic andesitic breccia.
