[en] This study investigated whether basalt features found in outcrops and cores could be identified in open borehole walls by the use of the borehole television camera. To answer this question detailed outcrop surveys were carried out in several locations in the Snake River Plain, Idaho. A similar type of survey was also done on several locations in the Snake River Plain, Idaho. A similar type of survey was also done on several cores from the Idaho National Engineering Laboratory, southeast Idaho. Borehole television logs were viewed to find similar basalt features that were noted in cores and outcrops. From these studies it was found that basalt features can be identified in open borehole walls by the borehole television camera. The basalt flows can be divided into four zones: an upper vesicular zone; a columnar zone; a central zone; and a lower vesicular zone. The upper vesicular zone can be further subdivided into four subzones: an upper vesicular subzone; a transitional subzone; a lower vesicular subzone; and a bubble train subzone. Some specific features found in the borehole TV logs were: bubble-trains, vesicle plumes, borehole extensions, and pipe vesicles. The overall distinctions for the zones were based on the vesicularity. An overall pattern of vesicles was found to be a progression of small numerous vesicles at the top of a flow which increase in size, but decrease in number, towards the center of the flow. The opposite is true starting at the bottom of the basalt flow where small vesicles are numerous, but increase in size while decreasing in number towards the center part of the flow. 14 refs., 3 figs
