介紹


蛇紋石是一個礦物群組總稱，組別內約有二十多種不同性質的蛇紋石，要清楚分辨各種蛇紋石有相當的困難。不過當中有三種比較重要的種類是較為人所認知的，分別是葉蛇紋石（Antigorite）、纖蛇紋石（Chrysolite）及利蛇紋石（Lizardite）



分佈地區


中國大陸遼寧省的岫岩縣，稱之為「岫岩石」或「岫石」，大陸其他各省份也有不少地方出產，中國文學中常提到的「葡萄美酒夜光杯」指的就是「酒泉岫石」[a]。「台灣墨玉」屬於蛇紋石的一種，與「台灣玉」[2]生長在一起，卻是由不同礦物種類組成，最大特色是帶有蛇紋線條、並有高成分的磁鐵礦石成分，顏色呈現深綠色或墨綠色。[3]

Volkswagen Group MQB platform

Image
The Volkswagen Group MQB platform is the company's strategy for shared modular design construction of its transverse, front-engine, front-wheel-drive layout (optional front-engine, four-wheel-drive layout) automobiles. Volkswagen spent roughly $60bn [1] developing this new platform and the cars employing it. The platform underpins a wide range of cars from the supermini class to the mid size SUV class. MQB allows Volkswagen to assemble any of its cars based on this platform across all of its MQB ready factories. This allows the Volkswagen group flexibility to shift production as needed between its different factories. Beginning in 2012, Volkswagen Group marketed the strategy under the code name MQB , which stands for Modularer Querbaukasten , translating from German to "Modular Transversal Toolkit" or "Modular Transverse Matrix". [2] [3] MQB is one strategy within VW's overall MB (Modularer Baukasten or modular matrix) program which also includes th...
