This paper, based on the novel wiseCIO (web-based intelligent service engaging Cloud Intelligence Outlet), presents digital archiving and transformed analytics via machine learning automata for intelligent UBC processes to liaise with Universal interface for human-computer interaction, enable Brewing aggregation (differing from traditional web browsing), and engage Centered user experience. As one of the most practical aspects of artificial intelligence, machine learning is applied to analytical model building and massive and/or multidimensional Online Analytical Processing (mOLAP) for more intelligent cloud service with little explicit coding required. DATA is central to useful information via archival transformation and analytics, and utilizable intelligence for Business, Education and Entertainment (iBEE) in support of decision-making. As a result, DATA orchestrates wiseCIO to promote ACTiVE XaaS that enables accessibility, contextuality and traceability of information for vast engagement with various cloud services, such as aCMS (archival Content Management Service), COSA (Context-Oriented Screening Aggregation), DASH (Deliveries Assembled for fast Search and Hits), OLAS (Online Learning via Analytical Synthesis), REAP (Rapid Extension and Active Presentation), and SPOT (Special Points On Top) with great ease.展开更多

In Southwest China there is an area of about 90 x 10 km where there are widely developed lowtemperature hydrothermal ore deposits. This area is the so-called vast low-temperature mineralizationprovince in Southwest China. This mineralization province is so large in area, so diverse in ore type andso numerous in mineralization belt that no other one could be found in other parts of the world. In recentyears of study the following features have been obtained. (i) This mineralization province is, for the most part, located in the southwestern part of theYangtze Block and extends to the Southwest Folded Zone and part of the Sanjiang (the three-river) Foldedzone adjacent to the Yangtze Craton.
