... the majority of ore deposits occur in metamorphosed host rocks. Among these deposits the substantial proportion... have been involved in the metamorphic episode(s) and consequently their texture and mineralogy may be considerably modified, often to the advantage of mineral separation processes. In addition, parts of the orebody may be mobilized and epigenetic features, such as cross-cutting veins, may be imposed on a syngenetic deposit. 2, record 2, English, - crosscutting%20vein
