Rock that is easily eroded is one of the essential ingredients of arroyo formation. In semi-arid climates, where there is little vegetation on the landscape, the abundant erosion products are washed downhill, where they accumulate in alluvial fans. This fan, composed of fine-grained sediment, has a small arroyo incised into it.Arroyo Rojo VMS deposit: geology and mineralogy 91. the ore body.
