Abstract

Abstract In the Southern Mountain Zone, many volcanic rocks that products of the Tertiary Volcanic Arc are exposed. In this zone, a lot of research has been carried out, but research about ancient volcanoes and the center of the ancient eruption has not been carried out thoroughly, so it is necessary to carry out further research related to the ancient volcanism of the Southern Mountains. The purpose of this research is to identify the preliminary study about existence of ancient volcanoes based on field and laboratory data with the aim of knowing the character, genesis, stratigraphic position and the potential of ancient volcanoes that produce many volcanic rocks. The research method used is a surface mapping method that supported by laboratory data such as petrographic and rock geochemistry using X-Ray Flourecence. In the study area, there were indications of ancient volcanoes based on image data, lithology, stratigraphy, petrography and geochemistry with facies association in the upper proximal facies. Stratigraphically, the Ancient Volcanic Rocks of Canndisari are under the Semilir Formation but not part of the Kebo-Butak Formation. The abundance of volcanic rocks can be used as class C mining materials. In addition, it is necessary to carry out further studies on the existence of hydrothermal alteration in the research area which may be used by local communities because altered rocks have economic value. Keywords: lava, genesis, volcanism, ancient, Candisari.

Abstract

The phenomenon of the existence of the Semadum volcano fossil located in Pisak Village, Tujuhbelas District, Bengkayang Regency, West Kalimantan has a Pliocene-Plistocene age with a clear cone-shaped morphology. The purpose of this study was to determine the behavior of the Semadum volcano in relation to the character of the magma, the pattern and typical eruptions and distribution of its products. The methodology used is field activity and geochemical analysis using X-Ray Fluorescence (XRF), Micro X-ray fluorescence (µXRF) and petrography. The Semadum volcano is geochemically composed of basaltic products, basaltic trachy andesite and dacite with basal to dacitic magma character which has a calc-alkaline affinity related to the subduction process, making Semadum volcano has 5 periods of effusive and explosive eruption activity with the Strombolian- Vulcanian type eruption with an eruption strength ranging from VEI < 2 makes the distribution of its product not too wide, it only centers on the body of the volcano which is the construction phase. Keywords: Volcano, Geochemistry, Petrology, Bengkayang, West Kalimantan
