This mineral association frequently shows simple accretionary features, such as crustifications (e.g., analcime I, Ba-bearing phillipsite-Ca, gismondine, rarely gmeliniteCa) and development of well-defined crystals or fibrous aggregates of natrolite and phillip-site-Ca growing from the walls into open space.

Our initial installations were quite successful, and we and our growing group of CORK collaborators have gone on to deploy similar instrumentation in a total of 11 sites (see map opposite) in three representative types of seafloor hydrological environments: spreading centers, where new seafloor is spreading outward from mid-ocean ridges (ODP Holes 857D and 858G), young mid-ocean ridge flanks (395A, 1024C, 1025C, 1026B, 1027C), and accretionary prisms, where sediments scraped off descending seafloor plates accumulate in front of overriding plates, like debris in front of a locomotive's cowcatcher (889C, 892B, 948D and 949C).
