Cave metagenome Raw sequence reads

The orthoquartzite Imawari Yeuta cave hosts exceptional silica speleothems and represents a unique model system to study the geomicrobiology associated with silica amorphization progression under aphotic and stable physical-chemical conditions. In this study, three consecutive evolution steps in the formation of a peculiar blackish coralloid silica speleothem were studied using a combination of morphological, mineralogical/elemental and microbiological analyses. Microbial communities were characterized using Illumina sequencing targeting near full-length and V4-V5 regions of 16S rRNA gene.
