Doran on Jurassic clastic breccia system origin of the glass rocks
Fu Tiao can achieve such a high content of rare earth; ② iron refractory pro-Os and Ir, Ni content of pro-and lower iron, do not have the characteristics of extraterrestrial cosmic dust; ③ iron ball, Co,[link widoczny dla zalogowanych], although the content of cr higher, but this is on the ball with the formation of Fe is relatively rich in Tiao and accompanying; @ Mo, As has a strong affinity to sulfur, and volcanic eruptions is closely related to the two iron balls in the Mo (24.8 , 30.6 × 10g'g), As (27.0,24.6 × 1O-6g ・ g-1) content is very high, which is extremely rare in the cosmic dust, volcanic eruption in the micro chondrules is common; ⑤ abundance of radioactive elements U in the three grains were as high as microspheres (15.9,7.9,22.4 × 10g ・ g),[link widoczny dla zalogowanych], which is dust in the universe never seen before . 4 Conclusion In summary, Toronto basin mouth and Qingyang groove monolithic breccias and clastic rocks glass microsphere particles in the neutron activation analysis results show that: (1) monolithic trench mouth and Qingyang not brecciated clastic rocks glass geochemical differences exist in principle,[link widoczny dla zalogowanych], mountain rocks glass. (2) 1111 monolithic breccia fragments of glass does not have the impact melt rock geochemical characteristics of glass, the element is relatively well without a loss of target rocks,[link widoczny dla zalogowanych], Th / U values is not a corresponding change. They all belong to the fire because of its volatile (3) monolithic rocks in the mouth two types of gravel fragments of glass microspheres do not have the cosmic dust particles should have at least extraterrestrial features,[link widoczny dla zalogowanych], they do not belong to external causes. Regional Geological Survey Team of Hebei Cai fortune, Hoban Shu, Shi Zhonghua comrades provide all the samples analyzed; Yao-Qi Zhou of post-doctoral and a useful discussion. In this well thanks.
