Volcanic rocks are the prominent host rocks in geothermal and volcanic systems in general, displaying heterogeneity. Although various external factors such as temperature, pressure, time, fluid chemistry, and subsurface geology have been thoroughly researched regarding the source of hydrothermal minerals in geothermal fields, the effect of hydrothermal alteration on volcanic hosts is still controversial in the literature. This review compiles data on the physical and mechanical properties of the host rocks composing volcanic environments exhibiting hydrothermal alteration or remaining unaltered. The considered data is originated from hydrothermal areas from Kuril-Kamchatka (Russia), Los Humeros (Mexico), Ngatamaraki, Rotokawa, Kawerau and Ohakuri geothermal fields and Mt. Ruapehu, Mt. Taranaki, and Whakaari volcanoes (New Zealand), Solfatara (Italy), Reykjanes, Nesjavellir, and Theistarereykir geothermal fields (Iceland), La Soufrière de Guadeloupe (Caribbean) volcano, and Merapi volcano (Indonesia).

火山环境中岩石的热液蚀变和物理力学性质：综述

火山岩是地热和火山系统中的主要主岩，表现出非均质性。尽管对于地热田热液矿物的来源，诸如温度、压力、时间、流体化学和地下地质等各种外部因素已经进行了深入的研究，但热液蚀变对火山宿主的影响在文献中仍然存在争议。本综述汇编了构成火山环境的主岩的物理和机械特性的数据，这些火山环境表现出热液蚀变或保持不变。所考虑的数据源自千岛堪察加半岛（俄罗斯）、Los Humeros（墨西哥）、Ngatamaraki、Rotokawa、Kawerau 和 Ohakuri 地热田以及鲁阿佩胡山、塔拉纳基山和法卡里火山（新西兰）、Solfatara（新西兰）的热液区。意大利）、雷克雅内斯、内斯亚维里尔和泰斯塔雷基尔地热田（冰岛）、拉苏弗里耶尔瓜德罗普岛（加勒比海）火山和默拉皮火山（印度尼西亚）。
