通过对碱泉子—洛包泉活动断裂带中碱泉子、红山口及洛包泉3 条活断层断坎微地貌的实测,尤其是对洛包泉活断层地衣直径及醉汉林胸径的实测,认为碱泉子活断层中全新世以来的垂直活动速率为0.99±0.02 m m /a～1.85±0.03 m m /a;红山口左旋正断层构成顺坡向断层陡坎,坎高1.6～7.0 m ,中全新世以来垂直活动速率为0.26±0.02 m m /a～0.95±0.06 m m /a,按其形成的水系左错1.6～2.8 m 计算,其水平活动速率为0.22±0.01 m m /a～0.38±0.03 m m /a,红山口活断层滑动速率为0.35～1.02 m m /a;洛包泉活断层地表破裂带长13 km ,断坎高3.6～14.8 m ,是由1914 年8 月5 日发生的7 12 级地震造成的。
Through the measurement of the broken ridge microfacies of the three active faults in the Alluvial Basins - Luotuoquan active fault zone, such as Alkaline Spring, Hongshankou and Luotuoquan, especially the measured diameter and the DBH diameter of the Lophanquan active fault, It is concluded that the vertical movement rate of Alkalon active fault since Holocene is 0.99 ± 0.02 mm / a ~ 1.85 ± 0.03 mm / a; the Hongshankou L-normal faulting constitutes a synclinal fault scarp with a ridge height of 1.6-7.0 m, The vertical movement rate of the world since 0.26 ± 0.02 mm / a ~ 0.95 ± 0.06 mm / a, according to the formation of water left fault 1.6 ~ 2.8 m calculation, the horizontal activity rate of 0.22 ± 0.01 mm / a ~ 0.38 ± 0.03 mm / a. The slip rate of the active fault of Hongshankou is 0.35-1.02 mm / a. The surface rupture zone of the active fault zone of Luofuangquan is 13 km long and the height of broken ridge is 3.6-14.8 m, which is caused by 7 12 earthquakes on August 5, 1914 Caused.
