Also known as Kazakhstan Block, Junggar Block, Junggar Craton, Kazakstania
Kazakhstania (), the Kazakh terranes, or the Kazakhstan Block, is a geological region in Central Asia which consists of the area roughly centered on Lake Balkhash, north and east of the Aral Sea, south of the Siberian craton and west of the Altai Mountains. The Junggar basin in Xinjiang, China, is also part of Kazakhstania, though sometimes referred to as the Junggar Block. Because the Kazakh terranes merged during the Late Ordovician as part of the Central Asian Orogenic Belt they are also referred to as the Kazakh Orogen. These terranes are located in what is today Kazakhstan, north-eastern
哈薩克大陸(哈薩克語:Қазақстания)是個史前小型大陸,範圍為現今的鹹海、西伯利亞大陸、阿爾泰山脈、巴爾喀什湖之間的區域,相當於大部分的哈薩克,加上準噶爾盆地,面積達1300萬平方公里。 哈薩克大陸被認為是早古生代的火山島弧與小型地塊的集合體。在奧陶紀時期,這些陸塊與島弧聚合成一個小型大陸,孤立於當時其他大陸之外。在石炭紀到二疊紀,西伯利亞大陸與哈薩克大陸碰撞,形成阿爾泰山脈。之後,西伯利亞-哈薩克大陸與歐美大陸(波羅地大陸部分)碰撞,形成乌拉尔造山运动,造成現今歐亞大陸內部大部分的盆地。 哈薩克大陸現今是個平坦的區域,只有卡拉干達東側的地勢較高(最高達1,565公尺)。該地區大部分氣候乾燥,屬內流區,有許多草原可放牧牛、綿羊、以及駱駝。在第四紀時期,這個區域過於乾燥,所以沒有冰河。這個區域的鈾產量,佔了全球產量的1/4,此外還盛產鉛、鋅、銻。南邊的圖蘭低地蘊藏大量天然氣。中世纪阿拉伯史家称吉尔吉斯草原。
