通过系统分析研究得出在鄂东地区地热资源热源主要来自于岩浆余热、放射性物质蜕变和地热增温,在出露的温泉附近,普遍侵入岩体的分布,特别是在英山罗田一带,温泉集中出露,根据调查,最大地热地温梯度达13.6℃/100 m,该地段地温场高和地温梯度异常明显,地温梯度是正常地壳2倍,属地热异常区,深部存在热源,可以认为鄂东地区是在挽近期仍有侵入活动的地带,可能有浅埋的干热岩体。
通過繫統分析研究得齣在鄂東地區地熱資源熱源主要來自于巖漿餘熱、放射性物質蛻變和地熱增溫,在齣露的溫泉附近,普遍侵入巖體的分佈,特彆是在英山囉田一帶,溫泉集中齣露,根據調查,最大地熱地溫梯度達13.6℃/100 m,該地段地溫場高和地溫梯度異常明顯,地溫梯度是正常地殼2倍,屬地熱異常區,深部存在熱源,可以認為鄂東地區是在輓近期仍有侵入活動的地帶,可能有淺埋的榦熱巖體。

The paper studies geothermal heat source in Eastern Hubei mainly from magmatic heat ,radioactive decay and geothermal through system analysis .In the hot springs near dew ,widespread intrusive rock ,especially in the Yingshan and Luotian hot springs exposed area ,the largest geothermal geothermal gradient of 13.6 ℃ /100m,the area of geothermal field and high geothermal gradient is very obvious ,the geothermal gradient is 2 times the normal crust ,belonging to the abnormal area .It can be that Eastern Hubei in Wan is still recent intrusion zone ,there is likely to be hot dry rock shallow buried.
