Badan Jaran Basin

situated in the west part of Inner Mongolia

is a poorly studied area in petroleum geology as its most areas covered by desert.In 1988

we took an area of 1600 km

near Saihantaolai Town on the west margin of Badan Jaran Desert as remote sensing test area.According to its remote sensing anomoly

a near-surface hydrocarbon geological exploration with the net point of 4 km distance was placed and ground object wave spectrum measurement was also made at the same time.The result shows that the sandy soil samples collected in the region contained methane

ethane

propane

butane and pentane

indicating that there was close relation between the anomalies of geochemical ex-ploration and remote sensing.NW stretching linar structures controlled the Meso-Cenozoic sediments while NE stretching linar structures controlled the hydrocarbon migration and accumulation.The principal geochemical exploration anomaly was situated at the cross section of the above mentiomed linar structures;the circular photographic anomaly of remote sensing fitted to the concentric circular anomalies of ΔC and C
