New exposures continue to be found in remote and often difficult terrains, where “on the spot” skills are of prime importance..In general terms the text has been arranged from the broad scale to the specific, and it should be realised that all scales provide valuable input for final interpretation. The topics covered include:.• Theoretical perspectives.• Initial recognition.• General field observations.• Detailed field observations (secondary minerals, boxworks).• Porphyry copper leached cappings. | | 出版日期 | Book 2011 | | 关键词 | Gossans; exploration-field technique; leached cappings; leached outcrops; porphyry copper; mineral resour | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-642-22051-7 | | isbn_softcover | 978-3-662-50714-8 | | isbn_ebook | 978-3-642-22051-7 | | copyright | Springer-Verlag Berlin Heidelberg 2011 |
