1中国东北小古里河高钾火山岩的水含量:对源区富钾组分的制约显示文摘近年来高钾(钾质)火山岩的成因问题越来越受到学术界的关注,特别是其地幔源区中富钾组分的来源.位于中国东北北部的五大连池、二克山、科洛(合称WEK)及小古里河玄武岩都是典型的高钾(钾质)火山岩.前人对这里做了大量的研究工作,但是对于源区中富钾组分来源还存在很大争议,主要包括:(1)来自于岩石圈地幔中含金云母的石榴石橄榄岩;(2)来自于过渡带中再循环的富钾占老沉积物.陈欢 夏群科 Jannick Ingrin 2015科学通报2015,60,24:17

3Typical Oxygen Isotope Profile of Altered Oceanic Crust Recorded in Continental Intraplate Basalts显示文摘Recycled oceanic crust(ROC)has long been suggested to be a candidate introducing enriched geochemical signatures into the mantle source of intraplate basalts.The different parts of oceanic crust are characterized by variable oxygen isotope compositions( δ^(18)O =3.7‰to 13.6‰).To trace the signatures of ROC in the mantle source of intraplate basalts,we measured the δ^(18)O values of clinopyroxene(cpx)phenocrysts in the Cenozoic basalts from the Shuangliao volcanic field,NE China using secondary ion mass spectrometer(SIMS).The δ^(18)O values of the Shuangliao cpx phenocrysts in four basalts ranging from 4.10‰to 6.73‰(with average values 5.93‰±0.36‰,5.95‰±0.30‰,5.58‰±0.66‰,and 4.55‰±0.38‰,respectively)apparently exceed those of normal mantle-derived cpx(5.6‰±0.2‰)and fall in the typical oxygen isotope range of altered oceanic crust.The δ^(18)O values display the negative correlations with the Eu,Sr anomalies of whole rocks and erupted ages,demonstrating that(1)the ROC is the main enriched component in the mantle source of the Shuangliao basalts and(2)the contributions of ROC varied with time.The basalt with the lowest δ^(18)O value is characterized by a significant K positive anomaly,highest H2O/Ce and Ba/Th ratios,suggesting that the mantle source of basalts with low δ^(18)O can also include a water-rich sediment component that may be the trigger for partial melting.Considering the continuous subduction of the Pacific slab,the temporal heterogeneity of the source components is likely to be caused by the Pacific slab subduction.Huan Chen Qun-Ke Xia Etienne Deloule Jannick Ingrin 2017Journal of Earth Science2017,28,4:0
4Water content of the Xiaogulihe ultrapotassic volcanic rocks, NE China: implications for the source of the potassium-rich component显示文摘Water has become an effective means to trace the mantle source of basaltic magmas recently. To investigate the source of the potassium-rich component in the Xiaogulihe ultrapotassic volcanic rocks of NE China, we measured the water content of clinopyroxene(cpx) phenocrysts by Fourier transform infrared spectrometry and calculated the H2 O content of the equilibrated melts according to the partition coefficients of H2 O between cpx phenocrysts and basaltic melts. The estimated H2 O content of the ‘‘primary'' magmas is low(0.36 wt%–0.50 wt%),within the range of mid-ocean ridge basalts and ocean island basalts, while it is obviously lower than that of backarc basin basalts and island arc basalts. The calculated H2O/Ce ratio of the ‘‘primary'' magmas is about 15, which might be similar to that of the dehydrated sediments(\100), but observably lower than that of the normal depleted mantle(DMM, H2O/Ce = 150–210). The low water content and especially low H2O/Ce ratio of the‘‘primary'' magmas demonstrate that the K-rich component of these ultrapotassic volcanic rocks seems unlikely tooriginate from K-bearing hydrous minerals(such as phlogopite) in metasomatic subcontinental lithospheric mantle.Combined with the low206Pb/204 Pb ratios, moderately high87Sr/86 Sr ratios of the bulk rocks and the high d18 O values of olivine phenocrysts, we suggest that the K-rich component in the mantle source of the Xiaogulihe ultrapotassic volcanic rocks may come from ancient continental-derived sediments which dehydrated significantly during subduction(e.g., dry K-hollandite).Huan Chen Qun-ke Xia Jannick Ingrin 2015Science Bulletin2015,60,16:0
