摘要: The pyrite of Almaden provides an excellent record the early history sediments. It is especially important as it appears on a regional scale constituent feature “Criadero Quartzite”. crystals are built up macromosaic nucleus surrounded by diagenetic cortex. Framboids display frequently mutual orientation, structure which unusual in “Rogenpyrit”. cortices different growth types (zonal, fibrous and sectorial).
