Reply to the Comment by Tan Mingxuan et al. (2017), on “A new Discovery of the Early Cretaceous Supercritical Hyperpycnal Flow Deposits on the Lingshan Island, East China”

<正>We thank Tan Mingxuan et al.(2017)for their comments stimulated by our short paper in the recent Acta Geologica Sinica(English edition).We are grateful for the opportunity to expand on the model of the supercritical hyperpycnal flow deposits in the Beilaishi section on the Lingshan Island,and to explain why the model proposed by Tan Mingxuan et al.(2017)cannot explain the bulk of

Compositional characteristics and Existing Forms of Major,Trace and Rare—earth Elements in Cassiterite,Dupangling Tin Ore Field,Guangxi

Trace elements in cassiterite,including Ta,W,Fe,Mn,Ti,Zr,V,Sc,Si,Al,In,Ga,Ge,Be,Bi,Ag,Sb,As,Cu,Pb,Zn,Co and REE,have been studied by many workers (Shan Zhenhua etal.,1998;Huang Zhou Tianren et al.,1987;Wu Qingsheng et al.,1988;Hu Zening,1988,Li Zhong-qing 1988 Mingzhei et al.,1988;Wang Lihua et al.,1988;Liu Kanghuai,1990).Up to now,however,most of the previous studies are concerned with trace-element variations in cassiterites of different occurrences and colors from different types of ore deposits,Data concerning the modes of occurrence of these trace elements are rare,except for the contention that Nb-Ta,Fe^2 -Mn-Fe^3 and W-Fe^3 may substitute isomorphously for Sn as pointed out by Zhou Tianren et al.(1987) and Moller et al.(1988).In this paper we are concerned with the compositional characteristics as well as the modes of occurrence of trace elements in cassiterites from quartz veins and greisens in the Dupangling tin field,Guangxi,based on multivariate statistical analyses.Tin mineralization in the Dupangling area is found associated with the medium-to fine-grained protolithionite-albite granite(γ5^2b) and its outer contacts.Cassiterite occurs,with wolframite,both in quartz veins in the contact and in greisens within the granite.^1) Spatially,greisens become dominant over quartz veins in the contact andin greisens with the granite.^1)Spatialy,gresens become dominant over quartz veins in going from the contact to the interior of the granite and with increasing depth.The greisens are of various shapes.The vein-shaped and the sheet-shaped greisens at the top of the granie are rich in quartz and the chambered greiens always constitute rich ores and contain abundant topaz or mica.Genetically,Sn,W mineralizations associated with the protolithionite-albite granite(γ5^2b) are considered to have been formed from fluid melt derived from the ore-forming magma responsible for the granite(γ5^2b).

THE MIANLUE TECTONIC ZONE IN SOUTH QINGLING AND ITS GEOLOGICAL SIGNIFICANCE

1. IntroductionThe discovery of the ophiolites (composed of mafic-ultramafics plutons, radiolarian silicalites and the basic metavolcanic rocks) in Mianlue zone was one of the most important progresses in the study on Qingling orogen in recent years (Zhang G W et al., 1995, 1996; Zhang Z Q et al., 1996; Yin et al., 1998; Lai, 1997; Lai et al., 1996; Meng et al., 1999). Many geologists got the conclusions as followings. (1) along the Mianlue zone, the oceanic crust developed in late Paleoz…
