Lurus Vulkan

Lurus volcano is a small volcano on the north coast of East Java, north of the larger Iyang-Argapura massif. It is not well studied, but could potentially still be active, and pose a threat to nearby industrial areas.

Beschreibung:

Probably related to its unusual position off the main volcanic aarc, Lurus' earliest magmas are unusual in their composition, because they contain extremely low silica, producing leucite-bearing rocks. Later magmas were more typical for subduction zone volcanoes (andesitic and trachytic).
