Abstract

The magmatic arc of Sumatra Island, which is indicated by the presence of the Barisan Mountains zone on the west side of Sumatra Island with a general direction northwest - southeast, makes Mount Masurai, which is administratively in Merangin Regency, Jambi Province, become one of the volcanoes on Sumatra Island. Geographically, the peak of Mount Masurai is located at coordinates 101o 51' 28.60" E and 2o 30' 09.19" S with an elevation 2915 masl. The eruption period of Mount Masurai is estimated to have occurred twice during the eruption period. Based on the lack of information about volcanoes, this research was conducted to determine the characteristic and distribution of pyroclastics from Mount Masurai. In the area around Mount Masurai, remnants of volcanic eruptions were found, in the form of pyroclastic flows and falls. From data collection based on the results of geological mapping and petrographic analysis, pyroclastic rocks were found in the area around Mount Masurai with lithology in the form of Andesite Breccia, Laharic Breccia Pumice Breccia, Lapilli stone and Tuff. This is reinforced by the results of petrographic analysis of rock samples which are dominated by the presence of a glass

Abstract

Tonalit di Daerah IX Koto Sungai Lasi, Kabupaten Solok ,Provinsi Sumatra Barat terbentuk akibat dari proses magmatisme yang terjadi di pulau Sumatra pada zaman Kapur. Tonalit pada daerah penelitian menerobos beberapa formasi yaitu formasi Slet Tuhur dan Batugamping Tuhur. Penelitian ini bertujuan untuk mengetahui kondisi geologi, geomorfologi, karakteristik dari tonalit, proses pembentukan tonalit dan tipe dari granitoid. Metode yang digunakan pada penelitian ini adalah survey lapangan yang kemudian akan dikorelasikan dengan analisis petrografi dan analisis XRF ( X-ray Fluorescence) sehingga akan didapatkan jenis batuan, seri magma dan lingkungan tektonik batuan. Berdasarkan hasil analisis diagram peccerilo dan taylor, diagram Pearce, dan diagram Mullen dapat diketahui bahwa intrusi tonalit memiliki seri magma sub-alkaline , magma yang berasal dari kerak benua dan berada di lingkungan tektonik island calc-alkaline basalt
