Mineral systems, hydridic fluids, the Earth’s core, mass extinction events and related phenomena
We argue that hydridic fluids from the deep-earth are an important fluid type in mineral systems. The Carboniferous through Triassic interval of Earth history is used to illustrate our hypothesis that flux of hydridic fluid is a causative link between many earth processes such as mass extinction, evolution of ocean chemistry, climate change, anoxia, large-scale volcanism and mineral systems. The Earth’s core is considered the dominant reservoir of hydrogen. An enhanced flux of hydridic fluids mobilizes the mantle and sustains tectonism and metallogenesis over 100s of millions of years.
