Bacterial mineralization in basaltic aquifers: implications for possible life in martian meteorite ALH84001: comment
Article Abstract:
Recovery of the martian meteorite ALH84001 offers a valuable opportunity for space explorers to provide evidence for the existence of extraterrestrial life. Space experts at NASA point new insights for the possibility of life on Mars since the meteorite features mineral surfaces comprised with minute balls with 50-100 nm diameter. Samples taken from the meteorite also highlighted the existence of bean-shaped or void forms, which can only be created by live bacterial cells that possess complex surface-tension spheres.

Synorogenic hydrothermal origin for giant Hamersley iron oxide ore bodies
Article Abstract:
Giant orebodies of microplaty hematite were found in the Hamersley province of Western Australia. These minerals were believed to have been formed during the early Paleoproterozoic period by driven heated fluids. Geologic mapping and basin analysis have made orogenesis research possible. Studies on the orebody shape and structure show evidence of ore formation may have occurred during the Ophthalmian deformation.
