The objectives of this paper are to: a) report on the detailed characteristics of the red-brown precipitates forming the sludge plumes in retention pond 4; b) describe and characterise the red-brown precipitate coating the organic mat over the pond
The objectives of this paper are to: i) describe the types of gelatinous, red-brown, iron-rich precipitates found in waterlogged surface layers of recently-formed, saline, sulfidic soils and compare these precipitates with those that befoul
boreholes in the same area and ii) elucidate the biogeochemical processes of iron mineral formation in both the gelatinous red-brown iron-rich precipitates formed during the wet season and yellowish iron-rich crusts formed in the dry season.
