一、引言一般来说,构成锰结核的主要铁锰矿物有10(?)水锰矿,衍射2线型δ-MnO_2(以下简称δ-MnO_2),衍射4线型δ-MnO_2(或7(?)水锰矿)和针铁矿。这些矿物一般都共生于同一个结核中,由于产地和赋存形式各异,其组成和量比各不相同。文中主要叙述10(?)水锰矿和2线型δ-MnO_2,并将涉及到7(?)水锰矿。本研究用反射显微镜观察了结核的微细 I. INTRODUCTION In general, the main iron manganese minerals that make up manganese nodules include 10 (?) Manganite, diffraction 2-δ-MnO_2 (δ-MnO_2) and 4-δδ-MnO_2 ) Manganite) and goethite. These minerals are generally symbiotic in the same tuberculosis, due to the origin and occurrence of different forms, the composition and the amount of different. The paper mainly describes 10 (?) Manganites and 2-line δ-MnO 2, and will involve 7 (?) Manganese ore. In this study, the microscopic observation of tuberculosis was performed using a reflection microscope
