本文对黑龙江东部晚古生代沉积岩中的碎屑锆石进行LA-ICP-MS U-Pb测年，目的是对中亚造山带东段的构造演化进行控制。张广才山泥盆系黑龙工组石英砂岩碎屑锆石的年龄群为~ 2503、~ 1833、~ 903、~ 802和551 ~ 403ma。小兴安岭泥盆系宝泉组石英砂岩锆石的年龄群分别为~ 2500、~ 800和489 ~ 425ma。这些年龄表明：(1)黑龙工组和宝泉组的岩石分别沉积于391 ma和413Ma之后；(2)这些岩石来自年龄为~ 2500Ma的地区，主要年龄群为~ 2500、~ 1833、903 ~ 800和551 ~ 403ma；(3)除了显生宙有新的下地壳增生外（CAOB内有大量显生宙花岗岩，εNd值为正），在这些晚古生代盆地（如上志盆地、汤源盆地和宝清盆地）附近，还出现了一些古前寒武纪基底的残迹，这些盆地位于松农—张广才山脉、兴安和额尔古纳地块等微陆块内。佳木斯地块东缘泥盆系黑台组石英砂岩碎屑锆石的峰值年龄分别为569、542、509和484Ma，与佳木斯地块马山群锆石的峰值年龄相近。这些年龄资料表明：(1)佳木斯地块东缘黑台组的沉积始于484Ma，(2)这些沉积物完全来自佳木斯地块。小兴安岭-张广才山脉和佳木斯地块晚古生代盆地中广泛存在480 ~ 550ma的碎屑锆石，小兴安岭-张广才山脉加里东期（445 ~ 499ma） i型花岗岩带，表明松南-张广才山脉和佳木斯地块的合并发生在早泥盆世之前，可能发生在早古生代晚期（~ 445Ma之后）。
We undertook LA-ICP-MS U–Pb dating of detrital zircons from Late Paleozoic sedimentary rocks in eastern Heilongjiang Province, NE China, with the aim of constraining the tectonic evolution of the eastern segment of the Central Asian Orogenic Belt (CAOB). Detrital zircons from quartz sandstone of the Devonian Heilonggong Formation in the Zhangguangcai Range yield age populations of ∼2503, ∼1833, ∼903, ∼802, and 551–403Ma. Zircons from quartz sandstone of the Devonian Baoquan Formation in the Lesser Xing'an Range yield age clusters at ∼2500, ∼800, and 489–425Ma. These ages reveal that: (1) rocks from the Heilonggong and Baoquan formations were deposited after 391 and 413Ma, respectively; (2) these rocks were sourced from regions with rocks as old as ∼2500Ma, with dominant age populations of ∼2500, ∼1833, 903–800, and 551–403Ma; and (3) in addition to new lower crust accreted during the Phanerozoic (as revealed by voluminous Phanerozoic granitoids with positive εNd values within the CAOB), it appears that several remnants of an ancient Precambrian basement occur adjacent to these Late Paleozoic basins (e.g., the Shangzhi, Tangyuan, and Baoqing basins) that occur within microcontinental massifs including the Songnen–Zhangguangcai Range, Xing'an, and Erguna massifs. Detrital zircons from quartz sandstone of the Devonian Heitai Formation on the eastern margin of the Jiamusi Massif yield peak age populations of 569, 542, 509, and 484Ma, similar to those obtained from zircons within the Mashan Group of the Jiamusi Massif. These age data indicate that: (1) deposition of the Heitai Formation on the eastern margin of the Jiamusi Massif had started by 484Ma, and (2) these sediments were sourced entirely from the Jiamusi Massif. The widespread occurrence of detrital zircons with ages of 480–550Ma within Late Paleozoic basins in the Lesser Xing'an–Zhangguangcai Ranges and the Jiamusi Massif, combined with the presence of a Caledonian (445–499Ma) I-type granitoid belt in the Lesser Xing'an–Zhangguangcai Ranges, indicates that amalgamation of the Songnen–Zhangguangcai Range and Jiamusi massifs took place before the Early Devonian, probably during the late stage of the Early Paleozoic (after ∼445Ma).
