What reading level is Economic Geology book?
To quickly assess the difficulty of the text, read a short excerpt:
2. Ores in the Basic Igneous-limestone Complex: The most interesting feature of this complex is the occurrence of small de- posits of contact metamorphic ore. The metamorphic rock is made up of calcite, augite, garnet, and less abundantly, zoisite and vesuvianite. Within the contact metamorphic rock are numerous pockets and nests of magnet te. The ores consist of ilmenite and magnetite. The most important and striking fea- ture of the district is the occurrence of highly titaniferous mag- netit...e of contact metamorphic origin.
3. Ores in the Limestone: The limestone in this district, wherever exposed, has been more or less replaced by iron. On Iron Hill the ore is principally siderite and limonite. In the small hill to the north the resulting product is chiefly a yellow ferruginous j asper and a highly siliceous limonite. In some places the siderite has been changed to hematite, but the structure and cleavage of the siderite are still preserved.
An analysis of the ore cited in the same paper gives the iron protoxide as 8.
