【Abstract】 The loss of volatile species CO 2 and TL intensity when calcite and limestone were shocked with different pressures was reported in this article. Incipient to complete CO 2 and TL loss occured over a pressure range of 10 to 70GPa. It was approached the relationship between shock-induced CO 2 loss and TL intensity when the natural mineral calcite and limestone were shocked by the meteorite. We developed a method with which the shock-induced CO 2 loss from calcite and limestone could be measured by TL intensity.更多还原
