SummaryGrowth twins, parallel growths, and necked crystals are described from zircon populations from granitic gneisses from the Precambrian of SW. Greenland. From observations of the distribution of internal growth zones it is concluded that whereas twinning takes place early in the growth history of elbow twins it can occur at any time during crystallization of the zircon. Parallel growth is attributed to a process of synneusis or attachment of zircons that have initially undergone separate growth histories. This implies that viscosity conditions of the rocks were low enough to permit the movement and collision of growing zircon crystals. The common occurrence of zircons with central constrictions, sometimes superimposed on transverse fractures, in zircon suites from the granitic gneisses is explained in terms of late-stage chemical corrosion accompanied by brittle fracturing.

Developing economies have been seeing an exhaustive rise of foreign direct investment (FDI) inflows all through the past two decades. Traditionally, India has pursued an enormously cautious approach; however, in 1991, India initiated the process of economic reforms towards a more open economy and got the sequence of processes to draw more FDI. The present study depends on the secondary data, and the time of the study is from 2004 to 2018. The FDI inflows have increased from US$5,777.8 million in 2004 to US$61,963.1 million in 2018. This article aims to present the descriptive analysis of FDI inflows in India during the selected period and also describes the long-term trend as well as the growth history of FDI inflows. The motivation behind this article is to make an effort to forecast the FDI Inflows in India for the coming years with the help of growth analysis, trend analysis and ARIMA (Autoregressive integrated Moving Average) forecasting. The result of future projections shows a positive trend indicating manifold increase in FDI inflows in India in the coming years.
