前言佩因特油田(Painter Reservoir Field)位于北美西部的逆掩断层带地区(图1),产层是三叠- 侏罗系的纳吉特砂岩。褶皱和逆掩断层带宽约100英里,从阿拉斯加经加拿大到阿利桑那长约3,000英里或更多些。在怀俄明西南部以及其邻近的州,这个逆掩断层带具有一系列界线清楚、向北延展的逆掩断块(图2)。罗伊斯等人(Royse et al.,1975)提出挤压变形的时间开始于晚侏罗纪并 Foreword The Painter Reservoir Field is located in the thrust belt of western North America (Figure 1) and is a Triassic-Jurassic Natjite sandstone. The fold and inversion cover about 100 miles of bandwidth, about 3,000 miles or more from Alaska via Canada to Arizona. In the southwestern Wyoming and its neighboring states, the thrust belt has a series of well-defined, north-extended thrust blocks (Figure 2). Royse et al. (1975) proposed that extrusion deformation started in the late Jurassic
