DEVELOPMENT OF STUDIES ON PRIMITIVE NOBLE GAS IN METEORITES(I):PHASE Q

The primitive noble in meteorite is from solar nebular and enteres into the meteorite through adsorption or dissolution of materials that constitute the meteorite before the formaion the latter or during its formation.Studies on primitive noble in meteorite show that the primitive noble of chondrites is concentrated in phase of chondrite,whose main component is called Q gas or P1 gas.In this paper,we have explained the reason for such terms and the process of separated phase from chondrite,composition of phase Q,position of phase in chondrite,and element abundance and isotopic composition of gas.Finally we have discussed the original significance of the primitive noble in meteorites.
