"Warm basins" whose geothermal gradient and terrestrial heat flow values are between "cold basins" and "hot basins" have an extensive formation area favorable for exploration and the resource potential and exploration prospects are between the two extremes.
Figure 11 compares the deep hydrocarbon potentials of source rocks in basins with different geothermal gradients in China as a function of depth, from which we can observed that "hot" basins expelled less hydrocarbon indicating they make up a smaller proportion of deep petroleum resources than their "cold" counterparts.
"Hot basins" characterized by a high geothermal gradient and terrestrial heat flow values are unfavorable for deep oil and gas exploration, only developing a limited fluid dynamic field below the depth of 4,500 m with limited formation area favorable for exploration.
Many are in the red-hot Barnett Shale basin under Fort Worth, Tex., where in 2006 Chesapeake paid $845 million for leases on 39,000 acres plus $181 million for the rights to drill on 18,000 acres under the Dallas-Fort Worth airport.
There is no evidence that the area subducted by the hot Shikoku Basin gradually extended eastward with time, which is predicted from the model proposed by Hall and others.
Furthermore, based on the volcanic activity in southwestern Japan, the subduction of the hot Shikoku Basin lithosphere beneath the Southwest Japan is considered to have occurred between 17 and 12 Ma concurrently from Kyushu to central Japan just west of the IBM Arc collision zone (Kimura et al., 2005).
Citing them as "remarkably fine material for photography," Jackson noted in his diary that "the delicate tracery in the white deposits forming the hot spring basins were rendered very effectively in our negatives".
The basin, the hottest of the park's hot spots, grew hotter still.
And Elizabeth Inchbald escaped the casting couch by throwing a basin of hot water on her pursuer.
Namgay brought tea to our tents at 6 30, along with a basin of hot water for washing.
