Deposit location

Oil shale deposits were formed in ancient lakes and seas by the slow deposition of organic and inorganic remains. The geology and composition of the inorganic minerals and organic kerogen components of oil shale vary with deposit locations throughout the world (1) (see also Fuel RESOURCES Petroleum). 

The Kishu deposit, located at middle Honshu, is associated with Kumano acidic rocks intruded into the Shimanto and Kumano formations. K-Ar age determination indicates that the activity of Kumano acidic rocks occurred at middle Miocene (14 1...

The XY deposit location was clearly discriminated using Pb and Zn from the high background values in lower B horizon soils, but not in upper B horizon soils. This finding contrasts the many protocols that emphasize the upper B horizon as the most appropriate for soil sampling. 

Bendigo is a classic example of a low-sulphide gold-quartz deposit located in a folded sequence of sandstone and shale of the Cambrian-Ordovician age (Ramsay et al. 1998 Goldberg et al. 2007). Regional soil geochemistry covers an area of 4,000 km. Sampling Grid 5x5 km. 134 samples were collected as can be seen in Fig. 2, titanium anomalies form sub-...

Soil sampling surveys are routinely used to explore for concealed mineral deposits. The giant Pebble Cu-Au-Mo porphyry deposit, located 320 km southwest of Anchorage, Alaska, provides an opportunity to test various sampling and analytical methods commonly used by the exploration community. 

Uranium oxides studied by in-situ methods (Bonhoure 2007), Bonhoure et al. (2007), this study), from deposits located in the vicinity of the unconformity (Fig. 4) or in the basement have nearly identical REE abundance and fractionation (HREE/LREE>1).

The younger kukersite shale, which economically is the most important oil shale resource of Estonia, occurs in two deposits. The Estonia deposit, located in the northeast of Estonia, underlies an area of 3000 km2 and comprises... 

The optimum catalyst and the optimum processing conditions for hydrodemetallation will depend upon the feedstock and the process application. To the extent that metal deposits determine the operating lifetime of the catalyst, knowledge of the intrinsic metal removal chemistry and molecular transport processes will enable prediction of metal deposition location within catalysts and will provide criteria for optimum catalyst design. 

Barataria Basin deposits are described by Kosters et al. (19) as lobe deposits located between the present Mississippi River and Bayou LaFourche. They consist of clays, mucks and true peats. True peat horizons are located in the top 1 meter of the section and developed during times of reduced clastic input from adjacent distributaries. Salinities of this site are relatively low, averaging 0.23 ppt in surface water and 1.11 ppt in porewater, because the site is about 80 km inland from the Gulf of Mexico, but are increasing with time. A cross section of the site is shown in Figure 4. 

Here, we report kinetic data measured during the ion-exchange process in the NH4 -Ni2+ system in the sample CMT-C [5,37], CMTC-C was obtained from deposits located in Tasajeras, Cuba (see Table 4.1) [5], The parameters characterizing the kinetics of ion exchange of NH4 and Ni2+ in the sample CMT-C [5,37], that is, R, De and the TEC, are reported in Table 7.3. 

The dependence of SCR activity of CuHM31 on its sulfur content with respect to reaction temperatures also shows the similar behavior to HM catalyst as shown in Fig. 4B. The catalytic activity reveals an exponential decrease with the sulfur content of the catalyst at 250 °C, while no deactivation is observed at 400 °C, despite the deposition of sulfur up to 1.78 wt.% on the catalyst surface. As discussed in the previous study, it is probably due to the deposition location of the deactivating agents on the pores of catalyst structure (ref 1). 

This research on pottery has three aspects. The ability to differentiate with trace elements different sedimentary units allowed us to conclude that pottery was produced from Nile deposits located in the immediate vicinity of the potter s workshop and kilns (25). The finer Plum Red Ware, most popular between ca. 4000 and 3400 B.C., and most common in cemeteries, was made from the same Nile sediments as the more common Straw Tempered Ware that dominated settlement ceramics. The Plum Red Ware was often fired in specific areas that may have behaved like natural wind tunnels (e.g., Locality 39 and 59 in Figure 1). Our more limited studies of Hard Orange Ware (a fine pottery most popular after about 3400-3200 B.C.) have shown that, although made from local Nile sediments, there was a significant... 

After panial oxidation of a coked catalyst, the first peak of the TPO profile disappears, and the activity for n-buiane dehydrogenation is completely recovered. A signiricaiu amount of graphitic carbon is detected by TEM and SAED examination of the residual carbon on Pt-Sn catalysts after partial oxidation. This implies that the first peak of the 1 PO profile corresponds to carbon deposits located mainly on the metal surface, wbile the second one derives from the more graphitC Iikc carbon located on the support.
