鲜水河断裂带是一个具有长期多次活动历史、性质较复杂的断裂构造。现今,仍有较频繁强烈的地震活动,是四川省著名的地震带。研究该断裂特征及其规律性,对于地质构造,地震地质及监测预报等,不无俾益。笔者于1980年前后,对鲜水河断裂带炉霍——道孚段作了一些调查,采集了一些岩石样品(见图1),进 The Xianshuihe fault zone is a fault structure with a long history of multiple activities and a complex nature. Nowadays, there are still more frequent and intense earthquakes and are the famous seismic belts in Sichuan Province. Studying the characteristics of the fault and its regularity will not make any difference to the geological structure, seismic geology, monitoring and prediction. Before 1980, the author made some investigations on the furnace section of the Xianshuihe fault zone - Daofu and collected some rock samples (see Figure 1)
