This location is particularly famous for exposing rocks at the crucial \u003cb\u003ePrecambrian\/Cambrian boundary\u003c\/b\u003e.\u003c\/p\u003e\n\u003cp data-path-to-node=\"4\"\u003eThis substantial specimen clearly exhibits the defining characteristics of a conglomerate. It is composed of numerous large, well-rounded to sub-angular \u003cb\u003eclasts\u003c\/b\u003e—or pebbles and fragments—set within a finer-grained matrix. The clasts show varied colouration, including whites, pinks, and earth tones, suggesting they were derived from different source rocks, likely including the \u003cb\u003eUriconian Volcanic Group\u003c\/b\u003e and the \u003cb\u003eErcall Granophyre\u003c\/b\u003e which underlies the area. The coarse, unsorted nature of the components suggests rapid deposition in a high-energy environment, such as an ancient stream or beach. The Ercall Conglomerate provides a tangible link to one of the most important periods in geological history, representing the transition from the relatively simple life forms of the Precambrian to the \"Cambrian Explosion\" of diverse life. Its position directly overlying older igneous rocks makes it a key geological marker.\u003c\/p\u003e\n\u003cp data-path-to-node=\"4\"\u003eThis specimen is an invaluable addition for \u003cb\u003egeology collectors\u003c\/b\u003e, \u003cb\u003eacademic institutions\u003c\/b\u003e, and \u003cb\u003eeducators\u003c\/b\u003e seeking a high-quality example of coarse clastic sedimentary rock from a globally significant locality.\u003c\/p\u003e\n\u003cp data-start=\"992\" data-end=\"1213\"\u003e\u003cstrong data-end=\"147\" data-start=\"136\"\u003eOrigin:\u003c\/strong\u003e The Ercall, Wellington, Telford \u0026amp; Wrekin\/Shropshire, England, UK\u003cbr data-end=\"199\" data-start=\"196\"\u003e\u003cstrong data-end=\"213\" data-start=\"199\"\u003eRock type:\u003c\/strong\u003e Conglomerate\u003cbr data-end=\"239\" data-start=\"236\"\u003e\u003cstrong data-end=\"367\" data-start=\"358\"\u003eSize:\u003c\/strong\u003e ~9(L) x 6(H) x 4(W) cm (see scale cube), 311 g\u003c\/p\u003e","brand":"Frugeo","offers":[{"title":"Default Title","offer_id":52531910312273,"sku":"FRU-CON-2","price":20.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0885\/9749\/6145\/files\/FRU-CON-2a.jpg?v=1764794225","url":"https:\/\/frugeo.science\/products\/fru-con-2","provider":"Frugeo Geology Store","version":"1.0","type":"link"}
