Features of ore-metasomatic zonation of ore area Freedom of Malmyzh gold-copper porphyry deposit

Present the ore-metasomatic zonation of the Freedom area, one of the ore centers of the Malmyzh Au-Cu porphyry deposit. The central part of ore-mineralization zones composes of quartz-sericite and biotite-K-feldspar metasomatites which carry relatively rich gold-copper. Flank zones are composed mainly of phyllic and propylites. These zones are characterized by increase content of lead, manganese and zinc. A positive correlation was found in two groups of elements: Mo–Cu–Au and Pb–Zn–Mn. Based on the analysis of the vertical change in the contents of ore components and their relationships, presumably, modern erosional level takes upper-ore position.

NATIONAL INTEGRATION AND ITS PROCESS IN INDONESIA

National Integration covers the arrangement of culture, territory, power, value and behaviour. Basically, the integration process is a horizontal change for the view of local to national or even international people and vertical change of elite group establishment having power legitimation. Integration process in Indonesia experiences up and downs and it will not enable to satisfy any and all related elements. It is started by national revival to establish the independent country, to find the fit and proper governance, to build a country to be strong in the economy field and then find the independence in liberal democracy nature. National integration is processed in accordance with the history development.

Vertical Variations of Boundary Layer Potential Buoyancy in Tornadic and Nontornadic Near-Storm Environments

Despite great strides in understanding the tornadic near-storm environment (NSE), at times it remains difficult to determine why some storms produce significant tornadoes, while others produce none, given similar pretornadic radar reflectivity and velocity signatures. Previous studies have shown that this is likely related to the potential buoyancy (θep) of the rear-flank downdraft (RFD) air. Unfortunately, to date there are few ways to operationally anticipate possible RFD thermodynamic character. Based upon previous research indicating that capping inversions may restrict much of the low-level RFD air to come from within the boundary layer, this study considers the relation of Δθep (vertical change in θep within the boundary layer below the cap) to tornadogenesis potential. This is because when a cap exists above a boundary layer and the descent of lower-θep air from aloft to the surface is potentially limited, then minimal Δθep may indicate more RFD air that has greater potential buoyancy. The Rapid Update Cycle (RUC) soundings used in this study and several observed soundings taken in the vicinity of violent tornadoes suggest that boundary layer Δθep shows promise as an additional means of discriminating between tornadic and nontornadic NSEs.
