Abstract

You may discover a specimen in your collection that is suffering from pyrite decay and it may already appear to be too late to save it. However, a pile of ash-like substance in a card tray might look like it is destined only for the bin but careful cleaning and simple stabilisation techniques may reveal a useful specimen underneath. If so, record it as fully as possible as soon as possible using either traditional techniques (photography and/or moulding and casting) or by using modern techniques such as photogrammetry, CTscanning, Micro CTscanning or laser scanning as the specimen will be prone to further deterioration in the future.
保持冷静,打电话给管理员:这只是黄铁矿的腐烂,你的标本可能还可以抢救
你可能会在你的收藏中发现一个标本正在遭受黄铁矿的腐蚀,而拯救它可能已经太迟了。然而,卡片托盘里的一堆灰状物质可能看起来只会被扔进垃圾箱,但仔细清洁和简单的稳定技术可能会发现下面有一个有用的样本。如果是这样,应尽快使用传统技术(摄影和/或成型和铸造)或使用现代技术(如摄影测量、ct扫描、微ct扫描或激光扫描)尽可能完整地记录下来,因为样品将来容易进一步变质。
