Geological investigations in the lassi granite mass (Central Sumatra)

The Lassi mass, Southeast of lake singkarak is a complex rock assemblage of permo-Carboniferous volcanics and sediments and Triassic Duringg Permo-Carboniferous volacanic and sediments and Triassic deposits, intruted by plutons and partly overlain by Tertiary sediments. During Permo-Carboniferous time this area was occupied by an elongated sea basin, in which thick sequence of bathyal and neritic sediments were deposited. Pelitic sediments dominated but contemporaneous volcanic products were also deposited.These late paleozoic early Mesozoic volcanic deposits (the Silungkang formation) have been studied petrographiccally and the results of this study, combined with the field relations, has led to the conclusion that they are autochtoneus deposits.
