Very few ancient stromatolites contain fossilized microbes.While features of some stromatolites are suggestive of biological activity, others possess features that are more consistent with abiotic (non-biological) precipitation.The company operates from a modern facility in Newport, South Wales, employing over 65 people at this site and another 30 around the world.IAC has a particular expertise in the application and manufacture of variable speed drive systems, along with vast experience in PLC and SCADA design.ABB resulted from the 1988 merger of the Swedish corporation Allmänna Svenska Elektriska Aktiebolaget (ASEA) and the Swiss company Brown, Boveri & Cie (BBC); the latter had absorbed the Maschinenfabrik Oerlikon in 1967.CEO at the time of the merger was the former CEO of ASEA, Percy Barnevik, who ran the company until 1996.1: no longer inhabited; "weed-grown yard of an abandoned farmhouse" 2: left desolate or empty; "an abandoned child"; "their deserted wives and children"; "an abandoned shack"; "deserted villages" [syn...
Lichen stromatolites are a proposed mechanism of formation of some kinds of layered rock structure that are formed above water, where rock meets air, by repeated colonization of the rock by endolithic lichens. Stromatolites occur widely in the fossil record of the Precambrian, but are rare today.

This may be a protective mechanism that affords evolutionary benefit to the colony in harsh environments where mechanical forces act to tear apart the microbial mats.
Thus these sometimes elaborate structures, constructed by microscopic organisms working somewhat in unison, are a means of providing shelter and protection from a harsh environment.
