I have a spectacular up to 2m-scale colonnade structure by clay deposits of an ancient deltaic sedimentary environments. It is similar to the cooling columnar joints of volcanics and volcaniclastics or sandstone in thermal contact. l described this occurrence as the first record within the clay. I would like to be sure of that ?
it is not surficial or sub-aerial like desiccation mud crack features.
Its a spectacular and definitely wonder of nature. Thankful for sharing this.
Thank you for interest
it is mainly montromolitic clay
but as it is unpublished article, we can share the whole detail of field setting, fracture morphology and characteristics, little results of mineralogical and petrographic identification and possible mechanism on the private mail
I have the willing for any scientific cooperation related to that.
You may please share information with me. My emailid is [email protected]
