This research was conducted to identify mineralogical characteristics of hydrothermallyaltered andesite in Kalirejo Village and surrounding areas, Indonesia. Rhyolite rocks bear a striking resemblance to granite, due to being classified as felsic rocks, except that rhyolite has a fine-grained texture with phenocrysts, which are small crystals sometimes embedded within the rock.

Stability of altered intrusive rock slopes in Kulon Progo Mountains, Yogyakarta Special Region, Indonesia (Unpublished doctoral dissertation). Indonesia Andesite stone is a type of extractive stone, which is experiencing a freezing and crystallization process above the ground. Whereas basalt forms a'a and pahoehoe surface forms, andesite generally produces blocky lava. SITE CHARACTERISTICS. Predicting volcanic rock distribution with magnetic data is based on the strong magnetic properties of the volcanic rock, as shown in Table 6.1.The magnetic susceptibility decreases gradually with lithology change from intermediate and basic rock, to volcanic breccia, andesite, dacite, tuff, and then to conglomerate, sandstone and mudstone. 1533.full.pdf .

Andesite is the volcanic equivalent of diorite. : European Atomic Energy Community, Ispra (Italy). Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava. Andesites are characteristic of subduction tectonic environments in active oceanic margins, such as the western coast of South America.
