Kremenasta ogrodja diatomej se ne<br />

razgradijo, temveč se nalagajo na<br />

dno morij in jezer.<br />

Diatomejske usedline, v katerih so<br />

ohranjene mikroskopsko majhne<br />

»škatlice«, so za znanstvenike<br />

odprta knjiga o okoljskih razmerah,<br />

značilnih za določene zemeljske<br />

dobe.<br />

Za branje in razlago pa je potrebno<br />

veliko znanja različnih strok.<br />

The diatom silica cell walls do not<br />

decompose rather they deposit in the<br />

bottoms of oceans and lakes.<br />

In diatom sediments the microscopic<br />

“cases” are preserved and are as an<br />

“open book” available to scientists of<br />

different fields to read about environmental<br />

characteristics of particular<br />

historical periods.<br />
