the so-called "black smokers", which are submarine hot springs associated with volcanic activity found in deep water along the mid-oceanic ridges. However, I soon shifted my interest to the shallower regions [...] disappointment to have traveled for so long and to find the springs gone. On this first snorkeling trip I found the underwater springs discharging gas and water at the same rate as when I left them two years ago [...] that precipitate when the hydrothermal fluids mix with ambient seawater. These iron minerals are found throughout the bay but preferably near vent orifices where they coat volcanic rocks and dead corals

in the area between 58 ° 00 'N , 32 °W and 58 ° 10 'N , 31 °W but suitable sediment ponds were not found in that section of the ridge flank. We were successful in identifying the third pond we visited as [...] mega-tsunami approximately 73,000 years ago. On nearby Santiago Island tsunami deposits had been found indicating run-up heights of more than 270 m . Hydroacoustic and seismic data were collected to determine [...] mineralization of the Murchison Greenstone Belt (2.97 Ga ), South Africa. The antimony enrichment, mainly found as stibnite ( Sb 2 S 3 ), is focused along the so-called “Antimony Line ( AL )” in quartz-carbonate

volcanic glass shows little, if any, evidence for dissolution. The FeS 2 precipitates were commonly found to be conjoined and planar aggregates, occurring in the center of the voids. Their maximum volume
