Reply to the comment by F. Tornos et al.

We welcome the discussion of our paper by Tornos et al. The epithermal character of the Hiendelaencina veins might have been an assumption in the early to mid 1980s, however, this early idea has been reaffirmed after many years of research involving fieldwork and mineralogical, sulphur isotopes, and fluid inclusions studies. The same applies to the alleged extensional frame, a tectonic episode now well documented not only in central Spain (Spanish Central System: Doblas 1987; Doblas et al. 1988; Doblas 1991) but in France (French Central Massif: Ménard and Molnar 1988; Malavieille et al. 1990; Munoz et al. 1992).The deposits are hosted by metamorphic rocks and the nearest volcanic outcrops to Hiendelaencina are those of Atienza (andesites; some 12 km northward). This is the reason why the relationships between the Atienza volcanics and the Hiendelaencina veins were initially regarded as obscure. These Stephanian-Permian volcanic outcrops are only local evidence of the late Variscan magmatism, which in the case of Hiendelaencina remained concealed. It is evident that the geologic environments of Hiendelaencina and Atienza are very different (see Discussion, p. 88 of the paper). As a direct consequence of this, the local structural conditions led to contrasted expressions of the late Variscan magmatism i.e. subaereal at Atienza and hypabyssal at Hiendelaencina.     

浙江中生代火山岩时代厘定和问题讨论：兼评Lapierre等关于浙江中？…

浙江中生代火山岩的时代长期以来存在不同意见,主要分岐为浙江磨石山群和浙西建德群时代窨是晚侏罗世、早白垩世、抑或晚白垩世。Ｌａｐｉｅｒｒｅ等（１９９７）的一文中据两条Ｒｂ－Ｓｒ等时线年龄,给出了如下论断;浙西火山活动（建德群）时代为１２４Ｍａ,划归为第一幕第一次岩浆事件;浙东（磨石山群）时代为９７Ｍａ,划归为第一幕第二次岩浆事件,而第二幕岩浆事件（指永康群）时代〈９７Ｍａ,本文就Ｌａｐｉｅｒｒｅ等文     

闽浙赣中生代火山岩研究问题浅议--兼与郑承意等商榷

通过当前东南沿海(尤其福建、浙江、江西三省)中生代火山岩研究对比,作者对郑承意等论文(2004)提出商榷,并讨论一些新的研究进展和成果。     

Comment on “Comparison of Michigan Basin crude oils” by Vogler et al.

Data is presented for Michigan Basin oils that indicate, in addition to the three distinct oil types, oils of mixed composition, intermediate between the Silurian and Ordovician types, also exist. These mixed oils which occur in Devonian (Detroit River) reservoirs are identified primarily by their isoprenoid and normal paraffin compositions.     

Comment on “The nature and origin of ureilites” by J. L. Berkley et al.

The record of primordial noble gases in ureilites imposes serious constraints on models of ureilite petrogenesis. It is argued that the inhomogeneous distribution between different mineral phases and the low ${}^{40}\text{Ar}{}^{36}\text{Ar}$ ratio in particular can only be satisfied with difficulties in the model proposed by Berkley et al.
