extremophile
extremophiles are microorganisms that have adapted so that they can survive and even thrive in extreme environments that are normally fatal to most life-forms. thermophiles and hyperthermophiles thrive in high temperatures. psychrophiles thrive in extremely low temperatures. – temperatures as high as , as low as halophiles such as "halobacterium salinarum" (an archaean) thrive in high salt conditions, up to saturation. alkaliphiles thrive in an alkaline ph of about 8.5–11. acidophiles can thrive in a ph of 2.0 or less. piezophiles thrive at very high pressures: up to 1,000–2,000 atm, down to 0 atm as in a vacuum of space. a few extremophiles such as "deinococcus radiodurans" are radioresistant, resisting radiation exposure of up to 5k gy. extremophiles are significant in different ways. they extend terrestrial life into much of the earth's hydrosphere, crust and atmosphere, their specific evolutionary adaptation mechanisms to their extreme environment can be exploited in biotechnology, and their very existence under such extreme conditions increases the potential for extraterrestrial life.
microorganism
the p-t-t paths are generally classified into two types: "clockwise p-t-t paths", which are related to collision origin, and involve high pressures followed by high temperatures; and "anticlockwise p-t-t paths", which are usually of intrusion origin, and involve high temperatures before high pressures. (the "clockwise" and "anticlockwise" names refer to the apparent direction of the paths in the cartesian space, where the x-axis is temperature, and the y-axis is pressure.)
