Sayatan Andesit Piroksen, bertekstur trakhitik, inequigranular, porfiritik. Fenokris terdiri dari plagioklas, piroksen, hornblenda, dan mineral opak yang tertanam dalam masadasar mikrolit plagioklas, piroksen, dan mineral opak. Presentase: Plagioklas (20%): hadir sebagai fenokris (12%), prismatik, subhedral-euhedral, menunjukkan kembaran Carlsbad dan Albit serta zoning, berukuran 0.2-1.5 mm, An33-35, sebagian tergantikan oleh mineral lempung dan mineral opak. Masadasar hadir berupa mikrolit plagioklas. Piroksen (17%): hadir sebagai fenokris (8%), 0.125-0.5 mm, subhedral, pemadaman paralel, orto dan klino piroksen. Sebagai masadasar piroksen nampak berupa mikrokristalin. Hornblenda (15%): hadir sebagai fenokris, 0.1-0.3 mm, subhedralanhedral, munjukkan belahan 2 arah. Mineral Opak (8%): hadir sebagai fenokris (2%), berukuran 0.020.4mm, dan sebagai masadasar berupa mikrokristalin. Mineral Sekunder: Mineral lempung (25%): ukuran sangat halus, ubahan dari plagioklas, piroksen. Mineral Opak (15%): berukuran halus, ubahan dari plagioklas, piroksen.
