Graphic art in Earth sciences, various ways to illustrate obvious and unobvious.

Graphic expression is essential in research and communication in Earth sciences, geology in particular, where modern graphic and visual technologies complement basic drawing skills which are still indispensable means of visual expression. We utilise graphic expression: a) to document fossils in process of their study, as well as to document geological structures and cave topography, b) to illustrate anatomy of fossils, in full range from single-cell organisms up to plant and animal morphology, c) to illustrate and describe field geological motifs what encompasses field sketches of rock outcrops, cartographical presentation of geological composition of an area, and illustration of geological relationships of certain area in the geological past, d) to illustrate morphological reconstructions of some organisms (eg. dinosaurs), the reconstructions of environments and geological relationships at some stages of the geological history, and e) to visualize composition of the Earth, migration of masses in the Earth interior, Earth's magnetic field, propagation of a tsunami, shape of ore bodies, etc. Basic drawing technique which illustrate static geological motifs is complemented by animations which illustrate time-controlled changes, such as changes of environments in relation to the changes in position of the sea-level. All of the tasks described demand certain degree of art skills of researchers, but in some companies they may enjoy support of professional technical staff. In any case, professional artist can not effectively and accurately illustrate a desired motif if the author-researcher himself is incapable of documenting it.
