“…Bulk samples of carbonate were dissolved using a buffered acetic acid technique (Crossey et al 1986) and the insoluble residue was analyzed by XRF and XRD. Using this dissolution Downloaded by [University of Sussex Library] at 13:54 22 August 2014 technique, iron and manganese should be oxidized and retained in the insoluble portion.…”

Unusual ferromanganese deposits are found in several caves in New Mexico. The deposits are enriched in iron and manganese by as much as three orders of magnitude over the bedrock, differing significantly in mineralogy and chemistry from bedrock-derived insoluble residue. The deposits contain metabolically active microbial communities. Enrichment cultures inoculated from the ferromanganese deposits produced manganese oxides that were initially amorphous but developed into crystalline minerals over an 8-month period and beyond; no such progression occurred in killed at Carlsbad Caverns National Park for their help and support. Larry Mallory contributed greatly to the design and debugging of the AO/INT procedure, and John Craig and John Husler often contributed their efforts to make analytical equipment and procedures work properly. We thank Jim Werker and Val HildrethWerker for help with field logistics in Lechuguilla Cave, Sue Barns and Tina Vesbach for assistance with the phylogenetic tree, and David Estes for sequence editing. Gratitude is expressed to Brad Tebo and three anonymous reviewers for constructive comments and criticism.controls. Phylogenetic analyses of sequences from clone libraries constructed from culture DNA identified two genera known to oxidize manganese, but most clones represent previously unknown manganese oxidizers. We suggest that this community is breaking down the bedrock and accumulating iron and manganese oxides in an oligotrophic environment.

“…Since Espitalié et al (1987) first published the correlation of H/C with HI in Fig. 77, subsequent efforts to confirm it as a general relation have been equivocal at best (Katz and Elrod, 1983;Grabowski, 1984;Crossey et al, 1986;Katz and Pheifer, 1986;Burwood et al, 1988;Scott and Hussain, 1988). Consideration of the discrepancies by Peters (1986), Larter (1988), and Baskin (1995Baskin ( , 1997Baskin ( , 2001 call into question the accuracy of many of the Rock-Eval analyses that contravene the linear correlation of H/C with HI.…”

“…The HI value is equal to the integral of the S2 peak (expressed in mg HC/g rock) divided by the TOC content. Accordingly, the HI value is related to the hydrogen richness of the OM (Crossey et al, 1986) and thus denotes the quality of the OM depending on its maturity and on its biological origin. Three main original OM types can be defined ( Figure 6) by analogy with the classic Van Krevelen (1961) classification: lacustrine (I: HI > 500 mg HC/TOC); marine (II: 150 < HI < 500 mg HC/TOC); and terrestrial (III: HI <150 mg HC/TOC) (Espitalié et al, 1977(Espitalié et al, , 1985b(Espitalié et al, , 1986.…”

Geochemical analysis of sedimentary organic matter in recent lacustrine sediments appears to be a useful tool in providing information concerning past environmental conditions. However, such analysis is often made without knowing the geochemical characteristics of the organic matter derived from the watershed and, more explicitly, its soils. The present work deals with (i) a geochemical investigation (Rock-Eval pyrolysis) of soil organic matter sampled in a lake watershed, and (ii) the study of the sedimentary organic matter trapped in the lake deposits. The research was conducted on Chaillexon Lake which was created by a rock collapse that dammed the palaeovalley of the Doubs River about 12 000 years ago. Since this event, the sediment trap provides a continuous palaeoclimatic record for the Postglacial period.Results obtained lead to two main conclusions. First, the variability of Rock-Eval pyrolysis values observed in soils modifies the common interpretation given to these parameters in the characterization of sedimentary organic matter. Indeed, variations in these parameters point not only to varying proportions of terrestrial and lacustrine organic matter in a lacustrine infilling but also to variations of the terrestrial supply linked with the evolution of vegetal cover in the catchment. The second conclusion is that the story of the Chaillexon lacustrine system is marked by a rather sudden soil and forest development at the Preboreal-Boreal transition (9000 BP).
