About 1400 placers and several dozens of ore gold deposits are known in the Amur gold-bearing province. Placers are to a large degree worked out, so the future of the province is seen to be in the discovery of the new gold deposits. The paper shows the dependence of the productivity and composition of the native gold placers on the size and formational affiliation of the placer-forming gold deposit. The reference couples have been identified: the gold deposit and the placer formed due to the erosion of its' upper part. For example, the Tokur gold-quartz deposit is a channel-fill placer in Toku

Abstract The paper presents the results of studies of diamonds from Early Jurassic sediments making up the Nyurbinskoe buried placer of the Nakyn kimberlite field, unique in diamond reserves. The main task is to identify diamond distribution patterns in the deposits of the Dyakhtar Stratum (lower deposit) and the Ukugut Suite (upper deposit) within the placer. A comparative analysis of the typomorphic features of diamonds from the upper and lower deposits of the placer was carried out.

Indonesia has several Titanium deposit types: beach placer, alluvial and lateritic types. The source of Titanium minerals in beach placer is derived from Tertiary Volcanic Rocks.Theoccurence of alluvial Titanium deposit is closely associated with cassiterite (tin minerals) alluvial in Bangka-Belitung Islands. The source of Titanium minerals (ilmenite) are derived fromweathering on tin mineralization hosted in metamorphic and granitic rocks within uplifted morphology areas. Lateritic Titanium deposits are formed by lateritization process in association with bauxite and nickel in Riau, Kalimanta

Abstract Deposits commonly encountered throughout the Pulp and Paper Industry are generally classified as microbial or non-microbial. Both of these categories can be further subdivided into a variety of classes, within which all common deposits can be placed. Despite the variety of deposits encountered, the corrosion problems posed by the presence of the deposits are few. Quite simply, environments beneath deposits promote localized attack, i.e. under-deposit attack. General corrosion can also be promoted by the chemicals and procedures used to remove the deposits from equipment and piping sys

Abstract The influence of oxygen on the cathodic behaviour of manganese dioxide was studied qualitatively by galvanostatic reduction of MnO2 deposited electrochemically onto stainless steel (SS), under aerated and deaerated conditions. The results indicate that the reduction takes place primarily at the interface MnO2/SS–substrate and leads to detachment of the deposit. Oxygen may participate in the reduction reaction being reduced itself and retarding the detachment process. This effect is diminished at higher current densities due to diffusion limitation of oxygen. It is concluded that the w

Summary The concentration of active chemical components that control deposits and corrosion in cooling water systems is often derived from a combination of techniques ranging from mass balance to measuring "traceable" components of the formulation. An example of the latter would be the use of molybdate which can be easily measured in cooling water systems but does not provide any corrosion or deposit inhibiting activity at the dose concentration. As it is a "tag" to the cooling water formulation its concentration does not necessarily directly reflect the concentration of active components in t

In natural gas transmission pipelines systems, there is a growing awareness of contamination due to the presence of sulfur vapor in the gas stream at sub ppm levels. Particularly at pressure reduction facilities, the sulfur vapor can desublimate out as solid elemental sulfur and then combine with other particle matter and trace liquids in the gas stream to form the observed contamination deposits. In order to better control the formation of the elemental sulfur, an improved understanding of the contribution that the design of pressure regulators make to this desublimation process is required.

The Browns Hole quadrangle is in Weber and Cache Counties of northern Utah and covers the eastern part of Ogden Valley, a rapidly developing area of the Wasatch Range. The Middle and South Forks of the Ogden River bisect the quadrangle and are important watersheds and recreational areas to the communities of Ogden Valley and the Wasatch Front. The towns of Huntsville and Eden are just west of the quadrangle, unincorporated communities with year-round residents are present throughout the quadrangle, and numerous summer-cabin communities are present in the eastern part of the quadrangle.

The Kipawa rare-earth element (REE) deposit is located in the Parautochton zone of the Grenville Province 55 km south of the boundary with the Superior Province. The deposit is part of the Kipawa syenite complex of peralkaline syenites, gneisses, and amphibolites that are intercalated with calc-silicate rocks and marbles overlain by a peralkaline gneissic granite. The REE deposit is principally composed of eudialyte, mosandrite and britholite, and less abundant minerals such as xenotime, monazite or euxenite. The Kipawa Complex outcrops as a series of thin, folded sheet imbricates located betw

Colonial National Historical Park (COLO) in eastern Virginia was established for its historical significance, but significant paleontological resources are also found within its boundaries. The bluffs around Yorktown are composed of sedimentary rocks and deposits of the Yorktown Formation, a marine unit deposited approximately 4.9 to 2.8 million years ago. When the Yorktown Formation was being deposited, the shallow seas were populated by many species of invertebrates, vertebrates, and micro-organisms which have left body fossils and trace fossils behind.

Based on the geological and petrographical studies and chemical analysis of drill-core and outcrop samples, the geology and mineralization at the Phu Lon area are revealed. The Phu Lon prospect is a Cu-Fe-Au-Ag skarn deposit of porphyry-related type. The copper- and iron-rich zones are hosted predominantly in the garnet-pyroxene skarn that is developed metasomatically at the contact between the diorite-monzodiorite intrusions and a marble with minor calcsilicate unit. The main stage of iron mineralization probably took place during the prograde garnet-pyroxene skarn formation and was genetical

This paper aims to shed light on changes in the saving behavior of microentrepreneurs in response to improved access to credit. This paper argues that it is necessary to extend the analysis to the shifting of assets between different forms of savings. The econometric analysis in this paper, which is based on data from IDB evaluations of its Micro and Small Enterprise Global Programs in Ecuador, El Salvador and Paraguay, concludes that increased access to credit induces borrowers to shift their savings from livestock, jewelry and other assets with low or negative returns into deposit accounts w
