I'm reading plenty of papers these days about carbonate concretions, dolomite formation in terrestrial environments and paleosols. Here's of a collection of the papers that I personally find most interesting and informative. There is currently a lot of cool stuff happening regarding dolomite formation in low-temperature environments. These articles are on the cutting-edge in my opinion. Of course it is but a tiny collection...
- Precipitation of low-temperature dolomite from an anaerobic microbial consortium: the role of methanogenic Archaea (Kenward et al., 2009)
- Microbially mediated carbonates in the Holocene deposits from Sarlieve, a small ancient lake of the French Massif Central, testify to the evolution of a restricted environment (Breheret et al.; 2007)
- Pedogenic origin of dolomite in a basaltic weathering profile, Kohala peninsula, Hawaii (Capo et al., 2000)
- Microbial precipitation of dolomite in methanogenic groundwater (Robets et al., 2004)
- Presence of sulfate does not inhibit low-temperature dolomite precipitation (Sanchez-Roman et al., 2009)
- The role of biomineralization in the origin of sepiolite and dolomite (Leguey et al., 2010)
- Origin of magnesium in clays from the Amargosa desert, Nevada (Khoury et al., 1982)

Thanks for posting these! I'm in the middle of carbonate petrology for my sed/strat class.
The one interesting thing I learned about was the relationship between temperature of formation and the nature of dolomite crystals in thin section. Dolomite crystals formed below 100C are fairly euhedral and those formed above 100C are anhedral.
That may well be though I found perfectly euhedral dolomites during my diploma thesis in thin sections that clearly formed during burial diagnesis above 100°C. It's not always that easy. :)
Hallo Lost Geologist
Schön, mal wieder von Dir zu lesen ! Und ich hoffe, deine Erkältung ist abgeklungen...ist doch super Exkursionswetter in diesem November !!
Morgen geht es wieder in den Oman
Glück Auf
Thomas / Bad Windsheim
Ja, die Langzeiterkältung klingt endlich merkbar ab! Viel Spaß im Oman!
