Yamamoto 2 对北太平洋中高纬度地区（包括白令海和日本海）硅藻泥和硅藻土-硅藻沉积物的地理分布和地质产状进行了综述。硅藻是北太平洋北部、白令海边缘、鄂霍次克海和日本海海底沉积物中发现的最丰富的微化石。北太平洋中高纬度边缘盆地是渐新世晚期—中新世早期的构造和火山活动形成的。早中中新世硅藻土夹硅质砂岩至粉砂岩，沉积于浅盆地。中新世中晚期硅藻土和硅藻泥岩是在深海缺氧底水条件下全球变冷和初级生产力增加而形成的。中新世晚期至上新世早期在有氧底水条件下形成的硅藻土和硅藻粉砂岩分布广泛。在上新世晚期至更新世期间，浑浊砂和/或淤泥覆盖并稀释了硅藻沉积物。这些沉积相变化的时间在北部是同时发生的
Yamamoto 2 The geographical distribution and geological occurrence of diatom ooze and diatomite–diatomaceous sediments were reviewed in and around the middle-high latitude of the North Pacific Ocean including the Bering and Japan seas. Diatoms are the most abundant microfossils found in the bottom sediments of the northern North Pacific Ocean, and the marginal Bering, Okhotsk and Japan seas. The marginal basins in the middle-high latitude of the North Pacific Ocean were formed by tectonic and volcanic activities in the late Oligocene–early Miocene. The early middle Miocene diatomite intercalated with siliceous sandstone to siltstone was deposited in shallow basins. The middle-late Miocene diatomite and diatomaceous mudstone was formed by global cooling and increased primary productivity under anoxic bottom-water conditions at bathyal depths. The late Miocene to early Pliocene diatomite and diatomaceous siltstone formed under oxic bottom-water conditions is widely distributed. During the late Pliocene-Pleistocene, turbidity sands and / or silts capped and diluted the diatomaceous sediment. The timing of these changes in sedimentary facies is simultaneous in the North
