本章从板块构造的角度考察加勒比地区的地质演化，由三个主要部分组成。首先，对加勒比海板块构造演化模式的一些主要构造制约因素进行了定义和评述。这些约束包括：(1)板块运动学框架：板块随时间的空间关系，源自北美、非洲、南美和法拉尔板块的初始重建和随后的相对运动，这些板块包括加勒比地区；以及(2)下列板块构造要素：(A)弧(弧=岩浆带)俯冲(岩浆活动)的极性和时间，(B)保存在逆冲带中的洋壳的形成(岩浆结晶)和侵位的年龄，(C)已知加勒比碰撞带内逆冲的时间和强度，(D)尤卡通盆地、格林纳达盆地和开曼海槽的古地理意义，以及(E)北加勒比和南加勒比板块边界带的发展。
This chapter examines the geologic evolution of the Caribbean region from a plate-tectonic perspective, and is composed of three major parts. First, some primary tectonic constraints on plate-tectonic models of Caribbean evolution are defined and reviewed. These constraints include:(1) the platekinematic framework: the spatial relationships of the plates through time, derived from an initial reconstruction and the subsequent relative motions of the North American, African, South American, and Farallón plates, which encompass the Caribbean area; and (2) the following plate-tectonic elements:(a) the polarity and timing of subduction (magmatic activity) of arcs (arcs= magmatic belts),(b) the age of formation (magmatic crystallization) and of emplacement of pieces of oceanic crust preserved in thrust belts,(c) the timing and vergence of thrusting within known Caribbean collision zones,(d) the paleogeographic significance of the Yucatá n Basin, Grenada Basin, and Cayman Trough, and (e) the development of the northern and southern Caribbean plate boundary zones.
