Rather worrying, as Tremolite is a component of the natural geology of Cornwall. It forms a major component of one of the Serpentine varieties encountered on the Lizard peninsula - historically popular as an ornamental stone - and may be found in some mineral lodes. 

In fact veins of asbestos can be found quite easily in the cliff exposures immediately behind and accessible from some of the popular beaches on the Lizard. Does this mean that they should be "Part 2A'd" ???

Hi all
 
as stated Tremolite is regularly found in tandem with Chrysotile as an impurity.  When considering serpentine asbsetos you would always consider the presence of amphibolous Tremolite.  If you are finding it on its own you need to consider whether it is associated with an activity or natural.  In some ways this is academic in as much as you really need to treat it the same as Crocidolite and amosite.  This rule applies to Actinolite and anthophyllite also.  Under a microscope all of these asbestiforms are similar to amosite in terms of morphology, it is only when you use dispersion stain/refrative index liquids that you work out they are something other than Amosite.  This is how this type of matter would be dealt with via a removal perspective..so see if you can cross fertilize.

Good morning,
 
Has anyone got any experience of dealing with Tremolite fibres in soil including potential sources? None of the other main asbestos fibre types are present and neither is there any visual evidence of asbestos containing material at surface or at depth in that location. Some articles indicate Tremolite could be the most dangerous form of asbestos fibres and it can be a contaminant of other asbestos materials.
