在内蒙古乌尼特煤田下白垩统巴彦花组中发现了保存较好的分散铜矿。含化石岩段可划分为6个层序层。根据其表皮结构特征，将分散铜矿的母质植物划分为Athrotaxites型、Manica型、Pterophyllum型、Zamites型、Ginkgo型、Baiera型、Czekanowskia型。从同一样品中获得了丰富的孢子和花粉，主要包括银杏属Ginkgoretectina、Bennettiteaepollenites、苏铁属Cycadopites、杉科Taxodiaceaepollenites和Podocarpidites，因此，分散化石的孢子花粉类型与由分散化石推断的亲本植物一致。巴彦花组沉积时期的气候可能为暖温带气候，并有季节变化。
Well-preserved dispersed cuticles were found in the Lower Cretaceous Bayanhua Formation of Wunite Coal Field in Inner Mongolia.The fossil-bearing rock member can be divided into 6successional layers.Athrotaxites-type,Manica-type,Pterophyllum-type,Zamites-type,Ginkgo-types,Baiera-types,Czekanowskia-types have been deduced as the parent plants for dispersed cuticles according to the characteristics of the epidermal structures.Also,abundant spores and pollen grains were obtained from the same samples,mainly including Ginkgoretectina,Bennettiteaepollenites,Cycadopites,Taxodiaceaepollenites and Podocarpidites.Thus,the dispersed fossil sporopollen types are in accordance with the parent plants deduced from the dispersed cuticles.Based on the assembling characteristics of the deduced parent plants,the climate in the sedimentary period of the Bayanhua Formation was probably warm temperate with seasonal changes.
