dark-grey to reddish-grey hematitic sandstones; we will refer in this paper to these two lithologies as the "red" and the "grey" sites. The generation of hematite in these Clinton-type iron ores has been shown [15,16] to be associated with extensive re- placement textures of calcitic fossil fragments,

Measurements were …The sandstone bed consists of two very different lithologic types: a hematitic sandstone and chalcedony-cemented quartzite. A sharp contact always segregates the two lithologic types.Natural hematitic sandstone samples show abnormal electrical behaviour.

Keefer Formation, a quartzose and hematitic sandstone with some mudstone. The Rose Hill and Keefer formations combine for a thickness that ranges between 670 ft (204 m) and 1,070 ft (326 m) (Gold, 2003). The Mifflintown Formation reaches a thickness of about 336 ft (103 m)

1. Introduction. 18 O/ 16 O ratios of natural materials are widely used as proxies for geologic, biologic and hydrologic processes. 17 O is another, less utilized, stable isotope of oxygen whose abundance relative to 18 O and 16 O is often described as a departure from a reference line with a slope close to 0.5 on a triple oxygen isotope plot …Picture and description of a large sandstone grinding stone that was used to grind red ochre from hematite and make plummets.Gold production from the northern Pataz district in the eastern Andean Cordillera of Peru has been sourced mainly from mesothermal quartz-carbonate-sulfide veins hosted by the Mississippian Pataz batholith.ABSTRACT Understanding petrographical, geochemical and electrical properties of rocks is essential for investigating minerals.

 fully and partially saturated hematitic sandstone sample (Aswan area, Egypt). The saturation of the sample was
 changed from partial to full saturation.The term 'hematite' itself might not be familiar to everyone, but its rusty red color definitely is. Sandstones are often reddish. This is because sand grains are coated with fine-grained hematitic powder. If soil is reddish, then it is also because of hematite. Even red granite owes its color to this mineral.The Paleocene Sangiali group represents Sangiali (limestone, glauconitic sandstone and shale), Rakhi Gaj (Girdu member, glauconitic and hematitic sandstone; Bawata member, alternation of shale ...Mauch Chunk Formation (Mississippian) at surface, covers 3 % of this area.
