Mineral textures give us an important information to clarify their geological phenomena occurred under various physical, chemical and/or biological conditions in the earth and/or planets. In this session entitled by Mineral Textures, the total 22 research reports were presented. The 15 reports of them concerned meteorites, and others, rock-forming and ore minerals. K. Tomeoka discussed the mineral-genesis in the proto-solar system based upon the microscopic texture analyses of chondrite meteorites in invited talk.
