The melange problem in geology was solved when Tony Barber of the University of London associated mud volcanoes in Timor and shale diapirism back in 1988.

“Mud diapirism: the origin of melanges in accretionary complexes?”
“Abstract
Chaotic melange deposits, a mixture of blocks in a clay matrix, have commonly been attributed to the mechanism of submarine slumping. In the oceans at the present day slumping does not occur on a sufficiently large scale to produce the quantities of melange seen in ancient accretionary complexes. In modern accretionary complexes, massive shale diapirism produces large volumes of melange, and is an entirely adequate mechanism to account for melanges in ancient complexes.”

Pretty common and destructive in the Indonesian archipelago

Faces in the mud.
I just had a look on Google Earth and it’s a fascinating place. I think the actual mud volcano is about 12.5 km to the north-west of Lokbatan, but all around the area there’s signs of geographical activity. To the east of the local airport it look like a huge construction site, but nothing has been built on the pads.

Does this help?

Oh, I’m sorry. I don’t know why that link didn’t go where it should have. Bubblecar has the right one.

And it looks the same as what I posted. It’s bafflin’.
speaking of breccia we read this recently, not particularly close to the ones here though
Abstract: Chang’e-4 rover discovered a dark greenish and glistening impact melt breccia in a crater during its traverse on the floor of Von Kármán crater within the South Pole Aitken (SPA) basin on the lunar farside. The discovered breccia, being 52 × 16 cm, resembles the lunar impact melt breccia samples 15466 and 70019 that returned by the Apollo missions. It was formed by impact-generated welding, cementing and agglutinating of lunar regolith and breccia. Clods surrounds the breccia-hosting crater were crushed into regolith powders by the rover’s wheels, indicating the regolith may be compacted slightly and becomes blocky and friable. Relative mineral fractions are estimated from the in situ measured spectra by a Hapke model-based unmixing algorithm. Unmixing reveals that plagioclase (PLG, 45 ± 6%) is dominant in the regolith, followed by almost equal fractions of pyroxene (PYX, 7 ± 1%) and olivine (OL, 6 ± 2%), indicating the regolith is likely related to noritic rocks. The regolith measured by Chang’e-4 rover was actually a highly mixture of multiple sources, with ejecta from Finsen crater being primary and possible contributions from Alder crater. Finsen and Alder craters are on the margin of the proposed impact melt pool produced by the SPA basin-forming event. Therefore, the ultimate source of the regolith might originate from a differentiated melt pool or from a suite of igneous rocks.
They are not the only sort of weird volcano.
Do you know of the washing soda volcano? In Tanzania. Ol Doinyo Lengai.
