当在岩心和(或)露头样品的有机质中观测到多次成熟的群体时,一般的假设是,较成熟的有机质组分是从较老的沉积物中经过再造而成的。卷峰铀矿床是这个规则的例外。在通过卷峰矿床的岩心样品中,可萃取出的有机质经常呈现出辐射损伤的各种现象(选择性氧化作用和(或)热变质作用)。取自卷峰之上的岩心样品含有孢子、花粉和有关的植物碎屑,它们有着一种均匀的蚀变质水平(热成熟)。然而,一旦穿过卷峰矿床,则可观测到热成熟的双层模式。当接近铀矿石最富集的地带时,较低的成熟水平就逐渐地过渡到较高的蚀变值。当岩心钻孔通过卷峰进入无矿岩石时,这种过程则相反。因为孢子、花粉、植物组织和 When multiple mature populations were observed in the organic matter of core and / or outcrop samples, the general assumption was that the more mature organic components were reconstituted from older sediments. The volcano uranium deposit is an exception to this rule. Extractable organic matter often exhibits various phenomena of radiation damage (selective oxidation and / or thermal metamorphism) in core samples passing through the volcanic deposits. Core samples taken from a volume peak contain spores, pollen and related plant debris that have a uniform level of eclogite (thermopregnancy). However, once through the volcano deposit, a two-layer pattern of thermal maturation can be observed. When approaching the uranium-rich zone, the lower maturity levels gradually transition to higher alterations. This process is reversed when core drilling passes through the entrapment into ore-free rock. Because of spores, pollen, plant tissue and
