The muddy volcanoes originate in the layer closer to the surface of the earth crust. The gas associated to the crude deposits in the sedimentary rocks, make their way towards the surface through clefts, reach the underground water layer, where they also involve the waters in their movement and on their way upwards, they also wash the clay and the other rock fragments they might meet with.
Since mud cannot exist without water, the muddy volcanoes are affiliated to Neptun's kingdom and it is the oilmen and hydrologists who are dealing with them.
But let's better have a look at the show put up at the surface. The volcanoes cones are not higher than 5-6 meters and the mud drops out on the slightly inclined slopes. A varied range of colours appears in front of our eyes. We discover the beauty of the mud which displays greyish and brown colours of a great variety and refinement. The chocolate borders of the crater are adorned with the white crust of crystallized salt and with belts of yellow sulphur mud, ochre or a shining black.
The pressure of the derrick gas defeats with great difficulty the viscous liquid which swells out, forms a hemisphere, splits and wearily falls down with a sigh into the boiling cauldron. If we bring a lit match closer to them a blue flame will braze out because the bubbles are mostly made of methane.
At the foot of the small volcanoes, the mud torrents have dried up acquiring shapes that remind the bark of the old trees and the honey comb.
Rezervatie naturală de tip geologic pe cca. 30 ha.,Vulcanii noroiosi sunt localizati īn Subcarpatii de Curbură , īn localitatea Berca, jud. Buzău, fiind formati datorită eruptiilor de gaze din pamīnt, care antreneza spre suprafata nămol si apă. Cunoscuti īn zona sub denumirea de pācle, vulcanii noroiosi au aceiasi structură ca si vulcanii adevarati, īn interiorul lor producāndu-se procese similare. Altfel spus avem de-a face cu niste vulcani in miniatură la care conurile nu depăsesc 5- 6m īnaltime, iar adāncimea de la care este aruncată spre suprafata "lava" este mult mai mica. In final acelasi rezultat , adica o suprafată īn mare parte aridă dar in celasi timp spectaculoasă.
Kindly regards,

Salut Ionela
Foarte frumasa vederea de la vulcanii noroiosi!
Imi place foarte mult texturile si formele de relief care ias aici bine in evidenta dar si efectul 3D superb pe care il dau compozitiei.
Singura chestie - ca probabil as fi iesit mai bine in evidenta fara oameni :)
...dar asa are valoare mai mare pt tine...
Oricum, Bravo si TFS
Horia
