Data about a thermal stream

Materials of the measurements spent on geothermal fields, in detail are not stated, as points are very numerous, located is close to each other, and the received average values are very high.

Other values - them more than 50 - can be grouped on sites as their arrangement in a direction from the north on the south.

1. Lakes of Northern Italy. Four large lakes (Garda, Lago-Madzhore, Komo, Izeo) and four smaller (Orta, Mergotstso, Viverone, Sirio) - all a glacial origin - have been studied Henelem. Average value of a thermal stream in these lakes after amendment entering on influence of a relief and osadkonakoplenie makes 67 yo 9 мВт/м2. Average values grow from the West on the east. After elimination of influence of a raising and denudatsii the Alpes average value decreases to 45 yo 7 мВт/м2. Probably, these values influence also lowering and osadkonakoplenie Padansky plain.

2. Romanja. In mergelistyh glinah three chinks by depth of 150-160 m. Nabljudennoe average value of a thermal stream are drilled makes 24,7 yo 3,3 мВт/м2; any distortions it is not revealed.

3. Northern Tuscany. Three chinks drilled to depth of 190 m in sandy glinah are investigated is very close one from another; nabljudennoe average value of a thermal stream was equaled 100 yo 4 мВт/м2, and temperatures have been obviously deformed by sea influence. Having brought the amendment on this influence, we receive value 99 yo 4 мВт/м2, and after the amendment on climatic changes 107 yo 4 мВт/м2.

Later values of a thermal stream for three chinks by depth from 100 to 567 m, drilled in sandy or alevritistyh glinah a sea or lake origin have been published. Average nabljudennoe value is equal 83 мВт/м2, but separate values vary from 95 to 60 мВт/м2. In the chink which has been passed to 567 m, on small depth local indignation is noted, but long-wave (regional) influences it is not revealed.
