Structures shaped like chevrons, or series of chevrons? Individual chevrons may include various sole marks described by Reineck & Singh in 'Depositional Sedimentary Environments' (e.g., fig. 102 in the 1975 edition). Series of chevrons may be of biogenic origin (trace fossils such as Protovirgularia) or inorganic origin (chevron marks; Reineck & Singh, 1975, fig. 112).
I agree with Andrew's answer. If the features occur with other sole marks (i.e. grooves, flutes, etc.), then it most likely is a "tool mark" reflecting small-scale deformation associated with an object dragging across a semi-cohesive substrate. If the asymmetry is clear, then its a handy paleocurrent indicator, as well as a clue to "stratigraphic-up" in structurally complicated areas.
One of the better photo examples I've seen is in the classic Pettijohn and Potter book "Atlas and Glossary of Primary Sedimentary Structures". Its plate 62 in my 1964 version . . .
