Geologia do Parque Estadual de Ibitipoca
Na regi縊 de Santa Rita do Ibitipoca - Lima Duarte, no sul do Estado de Minas Gerais, afloram rochas metassedimentares proterozicas, predominantemente, do Grupo Andrel穗dia. Essas rochas sofreram uma histria de deforma鈬o complexa, que produziram padres de interfer麩cia, registrados em tr黌 fases deformacionais: D1, D2 e D3.
Duas unidades tectono-estratigr畴icas distintas s縊 reconhecidas, separadas por falhamento de empurr縊 que dividem o Grupo Andrel穗dia em uma por鈬o superior alctone e outra inferior autctone.
Dados de campo e estruturais sugerem que os sedimentos que preencheram a bacia proterozica foram metamorfizadas na f當ies anfibolito, e deformada em regime tectnico compressivo, resultando na evolu鈬o tipo "nappe" de dobra, e desenvolvimento de zonas de cisalhamento no contato da unidade autctone e alctone.
O movimento tectnico principal foi dirigido de SSE para NNW.
Geology State Park Ibitipoca
In the Santa Rita de Ibitipoca - Lima Duarte region, south of Minas Gerais State, the Proterozoic metasedimentary rocks of the Andrel穗dia Group. Suffered a complex deformational history, resulting in interference patterns of folding, produced by three deformational phases, D1, D2 and D3.
Two distinct tectono - stratigraphic units are recognized, which are separated by a thrust fault and so dividing the area into na autochtonous part and na allochtonous one. Field and structural data suggest that Proterozoic sediments were metamorphosed under high - grade conditions and deformed compressive tectonic regime.
The result was the evolution of "nappe" - type folding and development of shear zones at the contact between autochtonous and allochtonous units. The direction of tectonic movement was SSE to NNW.
A 疵ea de Ibitipoca sofreu um tectnica com caractersticas polideformacionais, que gerou, em diferentes escalas, estruturas planares e lineares com v疵ias orienta鋏es e formas. Devido ao grau metamrfico elevado na 疵ea (f當ies anfibolito m馘io a alto), com seu apogeu durante D2, houve um mascaramento ou at transposi鈬o das estruturas D1.

Hi Ricardo,
I like the POV. There is great DOF and the colour contrast between the foreground and the background really help this image stand out. TFS.

Ola Ricardo,
nice the view as the presentation of this beautiful mountain scape view with the clarity and the sharpness of the foreground rocks to are so exciting and superb.

Hi Ricardo
Oh yes, I can see how if somebody is a lover of geology they would really enjoy a place like this.
Folding rocks eh? Thats pretty cool how mother nature does that over time.
It almost looks like dark snow formations.
I like the contrasting landscapes in the bg too, its a sweet mixture. Well done with the lighting in the fg
Cheers
Craig

Hello Ricardo,
it's very interesting to observe the geological formations that fill the foreground in a dynamic way and also lead us into the scenery. I like how they interact with the slopes and create a natural frame to the distant scenery. The textures are fascinating, the colours and the atmosphere very pleasant. Congratulations and thank you!
All the best, have a great evening,
Ourania
