互联网上搜到的“干涉波痕”实例
盎然是什么意思干涉波在现在的自然水体环境中极其常见,但其遗迹则非常稀少。许多从事地质工作多年的人不认识也就不足怪。俗话讲,物以稀为贵,特别是多种沉积现象集中出现在很小的地区内,更是弥足珍贵。
以下为从网上搜到的干涉波痕实例,不加翻译,原文照登。每个实例的来源均明确标出。同时希望博友们能够提供更多的实例。
INTERFERENCE RIPPLES (定义)
Interference ripples (a.k.a.“ladderback ripples”) are uncommon dimentary structures. They consist of diment surfaces showing two ts of ripple crests intercting at high angles. They form as ripples get developed on an already-rippled diment surface. They indicate the existence of two successive current directions.

The a-floor diments are compod of biogenic aragonite (CaCO3). The prominent ridges are symmetrical ripple marks, formed by a dominant, shallow-water, two-directional current. The smaller, ladder-like ridges are symmetrical ripple marks formed by a subordinant, shallow-water, two-directional current. The two ts of ripple marks form an interesting network of a floor ridges - interference ripples.

Interference ripples in quartzo sandstone (Berea Sandstone, lower Kinderhookian Stage,lowermost Mississippian).
The two successive current directions indicated bythe symmetrical ripples on this slab are left-to-right and up-and-down. The ripple t with ridges oriented up & down formed by a dominant shallow-water, two-directional current moving perpendicular to the ridge crests(= left-and-right direction, when looking at this upright slab).

The strange ripples in the Shepard formation are called interference ripple marks.
They form when two currents go against each other at ~90°. Fieldnotebook for scale.
