Description/Subtypes

End-member textures formed by reticulate ridges are honeycomb, linear, and accordion textures.
  1. (1)

    Honeycomb texture: fine polygonal texture, composed of interlocking, azimuthally symmetric sets of ridges (Fig. 1). Honeycomb texture is common within depressions (calderas, craters) and in valleys. They resemble intra-crater network dunes analogous to the terrestrial pattern of coalesced star dunes, which is formed from multiple wind regimes.

    Their wavelength is <few meters but may produce second-order sets of 15–20 m spacing and third-order sets of 50–200 m spacing. Fine-scale honeycomb texture may overlie network dunes, forming similar but smaller-scale patterns.

    Linear reticulate ridges: dominant curvilinear ridge...
