In this paper, factors controlling natural gas accumulation in the southern margin of Junggar Basin were mainly discussed by a comparison with generation and Kuqa Depression Tarim Basin. The are located on north south sides Tianshan Mountains respectively, they share similar sedimentary stratigraphy tectonic evolution history. recent several decades, many large fields have been found Basin, but...

A regional-scale stream sediment geochemical sampling was carried out with an averagesampling density of one sample per nine square-kilometre in Kiteto District, Manyara Region.A total 358 samples were collected and analysed for major traceelements by X-ray fluorescence (XRF) fire assay atomic absorption spectrometry(AAS) finish methods. In this study, Factor Principal Component Multivariate (F...

Approaching targets and placing instruments on them is fundamental to planetary exploration. Because of communications, power and operational limitations, it currently takes 3 full sol command cycles to accomplish this on Mars with the MER rovers. To accomplish single cycle instrument placement (SCIP) on multiple targets, we developed and integrated precision visual tracking, off-board continge...

Increased levels of robotic system autonomy will enable scientific exploration in previously unreachable destinations. Dexterous manipulator systems can be coupled with machine vision systems to increase perceptive capabilities and provide greater opportunities for scientific return through environmental interaction. Reliable autonomous vision systems are often specific to a certain task and qu...
