本文介绍了国外目前关于喷气岩的研究现状、现代喷气岩的新概念、喷气岩的基本类型、各类喷气岩的差别、海底喷气通道等问题。 作者结合近年来在秦岭泥盆系工作的资料,认为秦岭泥盆纪海槽北缘多以断裂接触关系与秦岭古陆毗邻,与其南缘相比,沉降幅度较大,随着该海盆的发展,形成了由一系列压性断裂为特征的活动性海盆边缘。这样的地质构,造条件似乎不利于岩浆侵入和火山喷发活动,而容易在深处形成一些热点或热区。该区泥盆纪地层中的一些Pb、Zn、Aq、Au等矿化及与其伴生的一些类似喷气产物的特征岩石可能与这些热区所派生的含矿气液有关。 陕西的双王和二台子金矿以富含钠长石为特征,可能与这种喷气热液有关。 最后提出了今后在本区开展工作应注意研究的几个问题。
This paper introduces the current foreign research on jet rock, the new concept of modern jet rock, the basic types of jet rock, the difference between various types of jet rock, and the submarine jet channel. Based on the data of the Devonian in the Qinling Mountains in recent years, the author thinks that the northern margin of the Devonian Trench in the Qinling Mountains is mostly adjacent to the Qinling ancient land and has a larger settlement than the southern margin. With the development of the basin , Forming an active basin edge characterized by a series of pressure fractures. Such geological structure, making conditions seem not conducive to magma intrusion and volcanic eruptions, and easy to form some hot spots or hot areas. Some Pb, Zn, Aq, Au and other mineralized rocks in the Devonian strata in this area and the accompanying characteristics of similar jet products may be related to the gas-bearing fluids derived from these hot zones. The Shuangwang and Ertaizi gold mines in Shaanxi are characterized by their abundant albite, which may be related to this jet hydrothermal solution. Finally, I put forward some problems which should be paid attention to in the work of this area in the future.
