震积岩

震积岩（英语：Seismites）是因地震而变形的沉积结构。德国古生物学家阿道夫·塞拉赫于1969年首次使用此词来描述地震变形层。现今，此词用于沉积层和由震动形成的软沉积物变形结构，包括超出层内的结构例碎屑岩脉或砂火山[1][2]。

Upper Ordovician of northern Kentucky中的震积岩
Dead Sea basin, 中的震积岩
Borden Formation中的震积岩

在野外现场观察时，请务必小心，避免与相似的非地震扰动沉积结构混肴[3][4][5]。区分震积岩与其他软沉积物变形的特征已有报导[6][7][8] [9][10][11][12][13][14][15]。但正式的、标准化的系统尚未开发出来。

地质学家利用震积岩与其他证据，研究一个地区的地震历史。如果能确定地震的年龄和分布，则可以评估地震灾害风险 [16] [17][18][19]。
