英文摘要 | A suits of middle permian strata consists of limestone, tuff and pillow basalts outcrop in aranbaotai area, locating the west of karakorum fault (taxkorgan fault) in karakorum mts. the basalts distribution in nw strike with 12km long and 4. 5km wide in west aranbaotai. the basalt has typical pillow structure, with pillow size from 0. 5m to 0. 8m, with stoma and amygdaloidal structure. the rock contents sio2 from 44. 14% to 48. 81%, tio2 from 1. 11% to 1. 83%, plotting in the boundary area of the picrobasalt, basalt, and tephrite basanite, belong to alkaline series. the rare earth elements (ree) contents vary from 54. 40 x 10(-6) to 139. 89 x 10(-6), with no eu and ce anomaly and (la/yb)(n) of 2. 87 to 6. 29. in the chondrite- normalized diagram, the patterns of the basalts are slight right dip type. the basalts contents variable large ion lithophile elements (lile) (e. g. k, rb and ba), and relatively deplete in the high field-strength elements (eg. nb, ta, zr, hf and p), show ti slight negative anomaly. the geochemical characteristics of the basalts show they have ocean island basalts, derived from the partial melting of spinel lherzolite. these middle permian basalts from aranbaotai area in karakorum mts. maybe present the location of the main ocean basin of the paleo-tethys ocean. |
