The Relationship between Fluid Flow, Structures, and Depositional Architecture in Sedimentary Rocks: An Example-Based Overview

Figure 3

(a) Example of how a fracture (white arrow) can control the formation and extent of iron oxide precipitates (black, dashed line) and how depositional architecture (blue arrow) may control the flow of oxidizing fluids (blue, dashed line); Hokianga, New Zealand. (b) Another example of how depositional architecture, here in the form of crossbedding, can control the extent of iron oxide precipitates; Taranaki, New Zealand.
